Abstract :
This paper describes some of the basic principles, the system models for the multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) communication systems. Several pilot-based channel estimation technologies, such as the Least Square(LS) algorithm, the Minimum Mean Square Error (MMSE) algorithm and the Linear Minimum Mean Square Error (LMMSE) are given for the MIMO-OFDM communication systems. The simulation system performances are also provided.
