New Channel Estimation Schemes for MIMO-OFDM Systems

Abstract:

Based on MIMO-OFDM systems,an adaptive modified factor EM channel estimation algorithm was proposed to improve the performance of channel estimation.Comparad to MEM,the adaptive modified factor was introduced in the algorithm,which reflected the impact of noise on signal more accurately and improved the estimation performance.The result of simulation showed that the algorithm proposed had better estimation performance.
