Abstract:
1. A system for estimating data transmitted by a plurality of transmit elements across a communications channel, comprising: a) a plurality of receive interfaces, each receive interface operative to receive a signal via the communications channel and output a respective sequence of received data elements; b) a space matched filter connected to said plurality of receive interfaces and operative to: c) a detector connected to said space matched filter and operative to process each filtered data element to produce a corresponding decision data set, the decision data set for each filtered data element includes a soft decision data set comprising a set of values, each value in the set of values being indicative of a likelihood or reliability associated with transmission of a corresponding symbol by the transmit element associated with the particular filtered data element and where the likelihood or reliability includes an a posteriori probability computed at least partly on the basis of:
