Signal decoding method for use in e.g. third generation radio communication field, involves diversity pre-decoding signal, estimating symbols and applying diversity pre-coding to estimated symbols, for two iterations

摘要

The method involves diversity pre-decoding a received signal to deliver a pre-decoded data, where the pre-decoding is the reverse of diversity pre-coding implemented during transmission of the signal. Symbols forming the signal are estimated from the pre-decoded data and diversity pre-coding is applied on the estimated symbols to provide an estimated signal. The above steps are iteratively performed twice. Independent claims are also included for the following: (a) a coding process (b) a receiver implementing a unit for decoding a received signal.
