The information exchange mainly relies on the computer correspondence, but corresponds takes the transmission method, with the sensing technology, the computer technology fuses mutually, has become in the 21st century the international society and world economic development powerful engine. OFDM(orthogonal frequency division multiplexing)is as one of thechannel estimation. Due to OFDM system adopting FFT technology, it reduces the complexity of the receiver greatly. So the application of OFDM technology in the domain of wireless communication has attracted wide attention. But OFDM is much more vulnerable to error of both channel estimation and how to obtain correct channel estimation efficiently is really important for OFDM system. This thesis will discuss channel estimation and channel estimation algorithm of OFDM system in the wireless broadband mobile communication environment.It mainly discusses the channel estimation algorithm for OFDM systems based on the block pilot, which includes LS(least square)algorithm,LMMSE(linear minimum-mean-square error)algorithm and LR_LMMSE algorithm. Finally the M language programming of MATLAB was use
