CDMA RECEPTION APPARATUS AND ERROR CORRECTION CODE SYMBOL SOFT DECISION METHOD

摘要

Demodulated symbol data obtained by RAKE combining a multi path is subjected to symbol soft decision, a reception state is detected from the demodulated symbol data, the demodulated symbol data after the symbol soft decision is delayed, an optimal mapping table is set from the reception state detection result, and the demodulated symbol data after the delayed symbol soft decision is again subjected to the symbol soft decision.
