Abstract:
1. A method of detecting in a receiver, comprising: (a) receiving a Q-vector signal by the receiver representing a set of P symbols where P and Q are both integers greater than 1; (b) estimating a first symbol of said set of P symbols; (c) subtracting an estimate of the portion of said received signal due to said first symbol estimate from step (b) to give a first interference-cancelled received signal; (d) soft-estimating a second symbol of said set of P symbols from said first interference-cancelled received signal; and e) providing a scaling for said soft-estimated second symbol from step (d) as a combination of (i) a detection scaling for said second symbol using said first interference-cancelled received signal and (ii) a first symbol estimate error term wherein said first symbol estimate error term includes a statistic relating to error in said first symbol estimate.
