Application background
Beamforming is one of the key technologies of MIMO. Multiuser MIMO system has multi-user interference and multi antenna interference, beamforming technology can effectively inhibit the interference, in the channel of simultaneous transmission of multi-channel parallel data stream to achieve diversity gain and multiplexing gain. This code is used for speed, various beamforming precoding test in multi-user MIMO communication system BER performance comparison.Key Technology
Multi user MIMO communication system in various beamforming precoding algorithm, the BER performance comparison of photosynthetic rate. We study a variety of classical beamforming methods including value  decomposition (Singular), Block (SVD), diagonalization BD (Zero), forcing ZF (Matched), filtering MF (), signal-to-leakage-and-noise Maximum  (), mean-squared Max-SLNR (Minimum ) and error MMSE (). Through simulation, we draw the conclusion: imatlab
