摘要

针对MB-OFDM超宽带(UWB)通信系统，提出了一种基于多信号分类(MUSIC)算法的子载波数盲估计方法。提出的特征值构造方法仅利用正交频分复用(OFDM)符号的信号自相关来估计子载波数。计算机仿真结果表明，该方法无论用于AWGN信道还是频率选择性衰落信道都具有良好的性能。

Blind estimation of subcarrier numberin in MB-OFDM ultra-wide band communications system

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.
