Research on the inter symbol interference mitigation for the MIMO-OFDM systems

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.
