Patent ID: 7142583

Claim:
A receiver for detecting and recovering data from received data bearing radio signal samples, said receiver comprising first and second detecting processors, each of said first and second detecting processors comprising a data store operable to store said received signal samples, an equaliser operable to combine said received signal samples with a plurality of equaliser coefficients, to produce refined signal samples representative of said received signal samples but with the effect of inter-symbol interference caused by multi-path propagation of said received radio signals at least partially reduced; a combiner means operable to receive the refined signal samples from said equaliser and to receive further refined signal samples, and to combine said refined signal samples and said further refined signal samples; and a data processor operable to receive said stored signal samples from said data store, wherein in said first detecting processor said further refined signal samples come from the second detecting processor, and in said second detecting processor said further refined signal samples come from the first detecting processor, and wherein the data processor of said first detecting processor is operable to receive second stored signal samples from said second detecting processor and to adapt the equaliser coefficients of said first detecting processor and the equaliser coefficients of said second detecting processor in dependence upon said received signal samples stored in said data store of said first detecting processor and in said data store of said second detecting processor, to the effect of increasing the probability of correctly recovering data from the received radio signal samples.
