BLIND ESTIMATION OF SUBCARRIER NUMBERIN IN MB-OFDM ULTRA-WIDE BAND COMMUNICATIONS SYSTEM

摘要：

In this paper , a new approach of blind estimation of subcarrier number based on mutiple signal classfication (MUSIC) algorithm is proposed for MB-OFDM ultra-wide band (UWB) communications system. The proposed eigenvalue-construct method only using signal autocorrelation of orthogonal frequency-division multiplexing (OFDM) symbols estimates the number of subcarriers. The computer simulations show that the proposed approach has a good performance whether it is used in AWGN channel or frequency selective fading channel.
