Abstract
In this paper, a blind channel estimator based on the aid of Pseudo-Pilot-Symbols(PPS) has been proposed relying on the character of OFDM system. Unlike pilots which are used for estimation of channel and must waste some useful bandwidth, the PPSs, whose power can be boosted 3 dB or 6 dB to suppress efficiently the additive noise, are useful data transmitted, thus efficiency of the OFDM system has been increased. Performance simulation of the proposed estimator including Mean Squares Error (MSE) of channel and uncoded Bit Error Rate(BER) have been taken, and the results show the estimator is efficient.关键词
