Abstract (in Japanese) (See Japanese page) 
(in English) In MIMO technology, feedback delay of channel state information is regarded as a cause of deterioration of transmission performance, and channel prediction using AR model is attracting attention as a technology for improving degradation of channel state information. In this report, we investigate parameter estimation for channel prediction equation from Doppler spectrum using Fast Fourier Transform (FFT), and investigate the channel prediction accuracy using the autocorrelation theory formula, in non-line-of-sight (NLOS) environment and line-of-sight (LOS) environment using the parameters estimated in LOS environment. As a result, it is shown that the prediction using autocorrelation theory formula in LOS environment reduces the mean square error about 10 dB for the prediction using the formula in NLOS environment. Also, the influence of the prediction error is shown when performing the MIMO eigenmode transmission based on the predicted channel on the channel capacity. As a result, it is shown that the using the formula in LOS environment can reduce deterioration of the channel capacity about 0.5-2 bit/s/Hz for using the formula in NLOS environment.
