DETERMINING COMBINER WEIGHTS AND LOG LIKELIHOOD RATIOS FOR SYMBOLS TRANSMITTED ON DIVERSITY CHANNELS

Methods and apparatus are presented herein for determining log likelihood ratios (LLRs) for code symbols. Pilot and code symbols are transmitted over diversity channels, which can be modeled as a slowly time varying system. A formulation for a multipath gain vector is derived herein based on the slowly time varying model. The multipath gain vector is then solved using iterative procedures. Using the solved multipath gain vector, the LLRs for code symbols are computed.
