Title: Channel equalisation for countering multi path propagation
Inventor: KELLER THOMAS
IPC: H04L27/01
Filed: 2000-10-16
Abstract: A compensating filter in a mobile telephone is used to compensate the effects of multi-path propagation of signals. The number of different paths of a signal, and the path differences between them will vary over time, therefore the compensating filter must be able to adapt to cope with changes in the interference it will compensate for. An equaliser in the telephone examines the output of the adaptive filter for a known synchronisation sequence then adjusts the filter to optimise the recovery of synchronisation data, effectively equalising the length of all the paths. A maximum path length difference to be used in the equalisation process is calculated and used in the equalisation process or supplied to other receivers. The limit may be small in an urban environment where there are numerous reflecting surfaces and large in the countryside which is flatter.

Title: Turbo-code decoding using a Soft Output Viterbi Algorithm (SOVA)
Inventor: NAKAMURA TAKAHIKO
IPC: H03M13/29
Filed: 2000-05-12
Abstract: The invention uses a Soft Output Viterbi Algorithm (SOVA) to calculate soft decision information for turbo-code decoding. Branch metrics and forward path metrics are calculated 201, 202, a comparison of two forward path metrics converging to respective states performed 203, and a differential value obtained 204. Soft decision information is calculated based on the comparison and the differential using a soft output viterbi algorithm 205. In an alternative embodiment branch metrics are calculated based on soft decision information of each received bit by comparing expected and actual bit values. Forward and backward path metrics are calculated on the basis of the branch metrics. Several embodiments are disclosed concerning the detail of calculating the forward and backward path metrics (figs 1-19) with a view to reducing memory requirements. In another embodiment decoding repetition is based on CRC errors (fig. 22), and in a further embodiment a switch enables two soft decision devices to process coded data simultaneously (fig. 23) for high speed decoding.

Title: Method and device for determining fluid flow velocity
Inventor: RUSSELL STEPHEN LINDSAY
IPC: G01F23/296
Filed: 2002-03-13
Abstract: A method for determining the surface velocity of a flowing liquid by cross correlation, using two modulated collimated light sources 1 and 2 impinging on the liquid surface with a detector system on a parallel optical axis 9. The light arriving at the detector 7 from the two light sources is separated into two channels using synchronous detection techniques and filtered so as to provide two time series which can be digitised and cross correlated to obtain the time taken for the liquid to flow between the 2 light spots on the liquid surface. The parallel axes of light sources and detector enable the system to accommodate to changes in liquid level without the need for moving parts or focusing systems. Detection of surface turbulence by the system is maximised by arranging the optical axis at an oblique angle to the liquid surface and by using a large aperture detector system.
