Abstract :
Inter symbol interference (ISI) and Inter carrier interference (ICI) are widespread in the orthogonal frequency division multiplexing (OFDM) communication systems. This paper mainly discusses the ISI mitigation in MIMO-OFDM systems. Combining with the V-BLAST method, we use a decision feedback technique for ISI cancelation and a cyclic reconstruction technique for ICI removal. Simulation results show that the proposed method can effectively Improve MIMO-OFDM system performance.
