The multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) communication systems can provide high data rate. Since channel estimation is an integral part of the receiver designs in coherent MIMO-OFDM systems, it is important to understand the basis of the channel estimation technologies. The basic system models are constructed for the MIMO-OFDM communication 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...
Inter carrier interference (ICI) are widespread in the orthogonal frequency division multiplexing (OFDM) communication systems. This paper mainly discusses two ICI self-cancellation algorithms, the data-conversion based ICI self-cancellation algorithm and the data-conjugate based ICI self-cancellation algorithm. The properties and the application environments are also given. Simulation results show...
