Abstract

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.
