Iterative receiver by joining beam-forming and decoding
Ma Chang · Chinese Journal of Radio Science · 2002
SDMA technique is available in increasing spectrum availability, but desired user's beam former steering other users frequently occurs in feedback MMSE algorithm after desired signal falls in deep fading, which affects the performance of beam forming. This paper proposes that the output data are encoded and interleaved to form the reference signal for second beam forming again, after first beam forming and channel decoding,which can overcome the beam forming steering error. Simulation results show the effectiveness of this method.
