A channel estimation scheme for MC-CDMA system
MC-CDMA 이동 통신 시스템에서 채널 추정 방식
Abstract
This paper presents the performance analysis of MC-CDMA system in reverse links acquired through the computer simulation. For channel estimation which is essential component of mobile communications, a modified alpha algorithm is proposed to estimate the channel sate for MC-CDMA system. In order to update the channel estimator of each subchannel, the modified algorithm uses the final hard-decision value in the receiver.
