摘要
以双带OFDM-UWB通信系统为背景,分析了基于FFT算法的三种均衡接收方法—迫零均衡、MMSE均衡和相位均衡。在Matlab的simulink平台上对信道CM1进行仿真,结果表明:为了使系统误比特率达到10-4的性能,采用相位均衡方法需要的SNR最低,仅为2dB;可见,OFDM-UWB通信系统相位均衡接收方法的系统性能比其它均衡接收方法都要好。
Three methods of equalization receiver, such as Poling equalization , MMSE equalization and phase equalization are analyzed by using FFT algorthim based on binary band orthogonal frequency-division multiplexing ultra wideband. Channel one is simulated on simulink by Matlab. The simulation results show that SNR is the lowest（only 2dB） in order that the BER is 10^-4 when phase equalization is used. So the phase equalization has better performance than the others based on OFDM-UWB communication.
