Patent

CA 2342081

In connection with transmitted space-time, trellis encoded, signals that pass through a transmission channel that is characterized by memory, improved performance is realized with a receiver that combines a decoder with an equalizer that selects the trellis transition, s, that minimizes the metric Image where r(k) is a signal received by the receiver at time k, h j (1) is related to the transmission channel that has a memory of length L+1 and terminates at a receiver antenna j, L1 is a selected integer less the L, and 1 is the lth multipath channel, s(k) are the trial symbols according to a certain transition and s(k) are the symbols that were previously decided.
