摘要

MIMO-OFDM以其卓越的性能成为未来通信技术的核心，其检测算法多种多样，但在实际应用中只有非线性算法得到广泛应用。首先简要介绍了ZF和MMSE准则，详细分析了V-BLAST算法和QR算法的非线性检测算法。然后研究了基于ZF准则和MMSE准则的ZF- osic、MMSE- osic、SQRD-ZF和SQRD-MMSE算法。最后通过MATLAB仿真比较了它们的误码率性能。

Comparison of V-BLAST / OSIC algorithm and the QR decomposition algorithm

MIMO-OFDM has become the core of future communication technologies for its great excellence, the detection algorithms are various, but only nonlinear algorithms are extensive used in practice. First, the ZF and MMSE criteria are briefly introduced, the nonlinear detection algorithms of V-BLAST algorithm and QR algorithm are analyzed in detail. Then the algorithms based on ZF criterion and MMSE criterion named ZF-OSIC, MMSE-OSIC, SQRD-ZF and SQRD-MMSE are studied. Finally the BER performance of them are compared, through MATLAB simulation.
