Title: OFDM synchronisation using moving average correlation filters for both pre-amble and post-amble
Inventor: ASJADI GHOLAM HOSEIN
IPC: H04L27/26
Filed: 2009-06-03
Abstract: A receiver for recovering frame synchronisation in an Orthogonal Frequency Division Multiplexed (OFDM) systems. The OFDM symbols include, within a repeating time frame, signalling (pilot) symbols and one or more data bearing OFDM symbols, the signalling OFDM symbol including a pre-amble guard interval and a post-amble guard interval. The receiver includes a signalling and guard detector, which includes a correlator comprising a first branch which includes a first moving averaging filter, which is arranged to form pre-amble average correlated samples by averaging a value of a plurality of pre-amble correlated samples within a moving window, the plurality of samples averaged within the moving window corresponding to a temporal length of the post-amble (Tb), a second branch which includes a second moving averaging filter, which is arranged to form post-amble average correlated samples by averaging a value of a plurality of post-amble correlated samples within a moving window, the plurality of samples averaged within the moving window corresponding to a temporal length of the pre-amble (Tc), a combiner, which is arranged to combine the averaged pre-amble correlated samples and the averaged post-amble correlated samples to form output correlation samples. In an embodiment, additional filters are provided in the first and second branches to reduce continuous wave interference. A post processing detector can detect the signalling OFDM symbol and moreover a synchronisation point derived from a centre of the signalling OFDM symbol with improved accuracy. The receiver finds application, for example, with DVB-T2 in detecting the P1 symbol.

In an arrangement for feeding a plurality of V.H.F. reception channels, reception horns 4 are located in the focal plane of electromagnetic lens 1 which intercepts the incident signal waves. Between the lens and the horns is located a plurality of parallel wires 2, lying in a plane at 45 degrees to the axis of the system, and each wire being at right-angles to the electric plane of polarization of the signal wave so as to cause no interference thereto. Energy from local oscillator 5 is radiated from horn 6 and impinges on wires 2 at right-angles to the system axis; it is arranged to be polarized electrically in the direction of wires 2 so that reflection occurs into the horns 2. Horn 6 is so located that its image in wire reflector 2 lies on the surface of lens 1. The Specification also describes a modification in which the horn 6 faces in the same direction as reception horns 4 and the reflector 2 is placed against the surface of lens 1 (Fig. 2, not shown) and a further modification using a parabolic mirror. In this (Figs. 3-5, not shown) reception horns 4 receive energy directly from the horn 6 fed by the local oscillator and it is the received signal which is reflected into the horns by the wire reflector, its plane of polarization being rotated, for this purpose, in reflection in the parabolic mirror by means of a second set of parallel wires located a half-wavelength away from the surface of the mirror and at an angle of 45 degrees to the first set of wires.

Abstract: Dyes containing both azo groups and disulphide groups are prepared by diazotization and coupling using components containing a reducible disulphide (-S-S-) linkage or by reduction and subsequent oxidation of an azo dye containing a thiocyano group. The specified dyes may be prepared by reduction and oxidation of 5-thiocyano-2-amino-toluene--> b -naphtol; reducing p-introaniline --> 1-phenyl-3-methyl-5-pyrazolone, diazotising and coupling to half a mole b -hydroxynaphthoic acid dithioanilide; coupling tetrazotized 4, 41-diaminodiphenyldisulphide to 2 mols of 1-phenyl-3-methyl-5-pyrazolone; and in the examples other similar mono- and disazo dyes are prepared.ALSO:Textile fibres are dyed in the following steps: padding with an aqueous composition comprising azo-disulphide dyestuff pigment and optionally a sulphur dye in reduced or non-reduced form which may be water-soluble or in pigment form, reducing the dyestuff oxidising, scouring and drying the fibres.  As azo-disulphide dyes there are used dyes containing a reducible disulphide group (-5-5-) connected between aromatic nuclei as well as azo groups (-N=N-), also dyes which upon reduction and oxidation form such dyes.  Examples of suitable dyes are 3 : 31-dimethyldiphenyldisulphide-4 : 41-bis-(azo-b -naphthol), 5-thiocyano-2-amino-toluene --> b -naphthol and the dyestuff formed by reacting m-nitro-aniline-->3-methyl-5-pyrazolone with 1 mol 2 : 4 : 6-trichloro-s-triazine and reacting the condensation product with 0.5 mole 4 : 41-diaminodiphenyl disulphide.  A number of modes of operation are described which comprise (a) applying the dye composition, drying, applying the reducing agent, steaming, optionally washing, exidising and finishing and (b) applying the dye composition containing a reducing agent, steaming and proceeding as in (a).  The specified reducing agents are sodium sulphide, polysulphide and sulphydrate as well as alkaline solutions of thiourea, sodium s-sodiocarboxymethyl thiosulphate, HOOC-R1-S-CS-S-R2-COOH (R1CR2 being alkylene).  The oxidising bath may have a pH of 4-6 and contain sodium bichromate and means for removing H2S gas may be required in some cases.  Examples of dyeing cotton, viscose and nylon fabrics are given and an apparatus for a mode of continuous operation is described.

A gas cock has a plug 15 to selectively control flow through an inlet 12 and outlets 13, 14, which is rotatable by a spindle 29 via an intermediate member 20, having a projection 21 to engage a notch 19 in the plug, so as to be axially movable against a spring 34 from a first position in which it engages the cock casing 11, by means of a projection 27, to a second position in which it is free to rotate the plug and control flow through the outlet 13 via a passageway 16. The connection between the spindle 29 and member 20 is formed by a pin 31 extending from the spindle to engage in either a slot 24 or a slot 25 in the member 20. The spindle is also formed with a pin 32 which co-operates with a fixed abutment 33 on the casing at a position corresponding to a cut-off position of the plug. To change the flow from the outlet 13 to the outlet 14, the spindle is displaced axially against a spring 30 to allow the pin 32 to move to the opposite side of the projection 33 and the pin 31 to move into the slot 25. Flow through a slot 17 and the outlet 14 can then be regulated. In either limit position of the plug the projection 27 engages a rib 36. The embodiment of Fig. 3, not shown, has a pin 31 which remains in the slot 24, and a projection 27 that can move in an extended slot 28 during movement of the pin 32 over the abutment 33.

Abstract: 1397072 Fluidic control circuits HAWKER SIDDELEY DYNAMICS Ltd 8 Sept 1972 [21 Sept 1971] 10450/71 Heading FIP [Also in Division F4]  A fluidic control circuit comprises a temperature sensor 17 producing an oscillating pressure signal, a device 39 for producing a reference frequency signal, which is compared with the signal from the sensor 17 in a comparator 18. Output signals from the comparator are fed to a control logic system which actuates bellows 61, 62 or 63 forming part of a stepping motor 21. The oscillating signals from the sensor 17 and the reference signal are converted to pulses by pulse shapers 32, 40. These pulses are fed to AND  gates 37, 42 respectively both directly and indirectly via delay flip-flops 36, 41. If the frequency of pulses from sensor 17 is greater or less than the frequency of pulses from the reference signal a pulse is emitted respectively from AND gate 37 or 42 and applied to AND gates 48, 49, 50 or AND gates 58, 59, 60. The other inputs to these gates are from the outputs of flip-flops 51, 52, 53 which also operate the bellows 61, 62, 63. A pulse from any of AND gates 48, 49, 50, 58, 59 or 60 is fed to one input of one of OR gates 55, 54, 56, or 57, switching off the flip-flop which is on, 53 in Fig.2, and switching on one of the other flip-flops (52 in this case) and operating the corresponding bellows. The three bellows drive the stepping motor 21 by displacing a wobble plate mounted in a gimbal. Teeth on the wobble plate mesh with an unequal number of teeth on an output gear which is accordingly rotated in a direction depending upon the sequence of operation of the bellows. The motor 21 controls a valve admitting warm air to an aircraft cabin to maintain the temperature at a reference level.
