Abstract:
A method for signal reception in a Multiple-Input-Multiple-Output (MIMO) communication system is provided. The method enhances the efficiency of signal reception in the MIMO system and simplifies the algorithms of signal reception and soft decoding metrics generation. In other words, soft decisions are generated according to correlations between metrics corresponding to least reliable bits based on MMSE linear estimation and noise variance estimation is provided to improve performance when an error is generated in channel matrix H estimation.
