Abstract(in English) This paper proposes a reduction scheme of CSI feedback amount in MIMO-OFDM eigenbeam transmission systems under spatially correlated transmission channels. The proposed method reduces the CSI feedback amount in the frequency domain. Computer simulations are carried out in order to clarify BER(Bit Error Rate), instantaneous C/N distribution and relative transmission capacity of the proposed method. As the result of simulations, the following things have been clarified: average BER declines by only one digit under highly correlated transmission channels even if the CSI feedback amount of 12% is reduced by the proposed method, and space diversity reception, or 2x3 MIMO system, can increase the relative transmission capacity by 7% comparing with 2x2 MIMO system.
