Abstract (in Japanese) (See Japanese page) 
(in English) Vector Coding (VC) is a transmission scheme that can obtain path diversity gain while orthogonalizing receive signals. It has been shown that VC can provide better bit error rate (BER) performance than orthogonal frequency division multiplexing (OFDM) that has already been put to practical use in wireless local area network (LAN) etc. In VC, the eigenvectors of the channel matrix should be available at both transmitter and receiver, and it can achieve the best BER performance under the perfect CSI. However, in practice, the influences of channel estimation error and feedback delay cause the performance degradation of VC. Until now, to the best of authors’ knowledge, the effect incurred by estimation error and feedback delay on the performance of VC has not been elucidated. In this report, we analyze VC system in the presence of channel estimation error and feedback delay. We elucidate the optimum transmit and receive weight in the presence of channel estimation error and feedback delay. We also confirm it by computer simulation.
