Title: Anti-aliasing zero-padding before IFFT in an UWB MB-OFDM system
Inventor: EDWARDS FRASER
IPC: H04B1/69
Filed: 2006-09-26
Abstract: In Ultra Wide Band (UWB) communication via a Multiple frequency band Orthogonal Frequency Division Multiplex system (MB-OFDM), aliasing in an Inverse Fast Fourier Transform (IFFT, fig. 2) is avoided by zero padding the data points beforehand instead of filtering out the alias afterwards (fig. 3). The number of appended, pre-pended or interleaved zeroes is typically similar to the size of the data set, thus doubling the data set in size (128 points at 528 MHz in fig. 2, 256 points at 1024 MHz in fig. 5). After zero padding and IFF transformation, Digital Analogue Conversion (DAC) and filtering can be carried out to reduce the alias still further. The apparatus can be implemented as a Digital Signal Processor (DSP), an Integrated Circuit (ASIC) or a Field Programmable Array (FPGA).

Title: A clock-and-data-recovery circuit, especially for a SERDES receiver
Inventor: TAKEUCHI MASAHIRO
IPC: G06F1/06
Filed: 2007-01-09
Abstract: A clock-and-data-recovery (CDR) circuit includes a data sampling circuit (101), a phase comparator (102), a phase controller (103), and a phase interpolator (104), together formed as a loop. The data sampling circuit samples serial input data, and the phase comparator receives an output from the data sampling circuit to detect the phase relationship between a clock signal and the data. The phase controller outputs a phase-control signal based on the result of phase comparison. The phase interpolator receives a multi- phase clock signal composed of plural clock signals with different phases, and supplies to the data sampling circuit a clock signal having the phase interpolated based on the phase-control signal. The phase control signal is selectively influenced by a control circuit 111 outside of the loop. For example, the phase controller may receive a test phase control signal or/and a phase offset signal. The clock-and-data-recovery circuit may further include a second phase interpolator (105) and a second data sampling circuit (106). Preferably, the second phase interpolator has a variably-set threshold level for sampling the data. The invention enables the measurement of the operational margin of the CDR circuit.

Abstract: A method of detecting TV periodic activity patterns when viewing audio video content comprising logging activity data, suppressing the activity log to remove non-relevant data, and using signal processing to convert the data to frequency responses which are analysed to detect the activity patterns of the user. The stored activity data is the time spent by a household on a periodic basis performing an activity such as selecting a television channel, playing back a PVR recording, requesting non-broadcast content and fast-forwarding / rewinding, each activity having a defined attribute such as programme title, genre, channel name, time and language. A user profile is generated, the non-relevant data is suppressed to analyse trends such as weekday and weekend viewing patterns, and the time domain data is converted into the frequency domain using a Discrete Fourier Transform, Discrete Cosine Transform, Discrete Hartley Transform or Wavelet Transform. The user's TV habits are used to schedule targeted advertisements or generate a favourite channel list / EPG in order of popularity.

Abstract: 527,084. Electrodeposition of metals. DU PONT DE NEMOURS & CO., E. I. March 30, 1939, No. 10021. Convention date, March 30, 1938. [Class 41] In the electrodeposition of metals such as zinc, cadmium, copper and brass, in which the metal of the anode replenishes the plating bath, the anode metal is alloyed with a small proportion of a metal which during electrolysis does not dissolve in the plating bath but forms an insoluble compound. The amount of added metal may be regulated so that the anode and cathode efficiencies are the same. Magnesium and calcium are suitable alloying metals. In the case of copper, small additions of magnesium reduce the anode efficiency very considerably and the anodes may be used as supplementary anodes. Small additions of other metals such as lead, aluminium or mercury may be made to the anodes.
