The pre-coding for multipath channel in a MIMO system

摘要

The pre-coding for multi-path channel in [challenge] MIMO system. Technology for pre-coding data for multi-path channel in [MEANS FOR SOLVING PROBLEMS] MIMO system. In one way, it is coded according to the coding scheme of one or more, the data provide coded data. (Ie, the symbol is mapped) is further modulated according to a modulation scheme of the one or more, which gives the modulation symbols. Equivalent channel response (eg, provided by the receiver) the estimated response of the MIMO channel is obtained and is derived based on the response of the feed-forward filter of a decision feedback equalizer and MIMO channel responses estimated. Thereafter, the precoded based on the equivalent channel response, the modulation symbols and provides a precoded symbols. Based on the MIMO channel response is estimated which is (- temporal pulse - for example, the space using shaping) is pre-conditioned further, giving the symbols are pre-conditions for transmission over the MIMO channel. The feed-forward filter may be adapted based on a minimum mean square error (MMSE) criterion.
