MMSE Demodulation in a Multi-User MIMO System

摘要

A method and apparatus is provided for demodulating a desired data stream in a MU-MIMO communication system where only the precoder for the desired data stream is known a priori. The receiving terminal according to various embodiments of the present invention estimates the precoder for one or more interfering data streams. The receiving terminal can then use the known precoder for the desired data stream and the estimated precoders for the interfering data streams to perform MMSE demodulation.
