Abstract
Based on the analysis of preceding principle in MIMO-OFDM system, an improved codebook design method is presented in this paper. Combing direct quantization method and Householder matrix, the proposed schemes has a better tradeoff performance than traditional quantization method. Simulation result s also shows a better performance than traditional method especially in 3 and 4 transmit antennas.Keywords
