In view of the effect of frequency-selective fading of ultra-wide band and carrier jitter on the performance of the system of multi-band orthogonal frequency-division multiplexing ultra-wide band(MB-OFDM-UWB),this paper proposes a scheme that uses filter bank to realize fast Fourier transformation(FFT) of the OFDM system.The complexity of the system is reduced by optimizing the structure of the filter and algorithm of the prototype filter.The result shows that the complexity of the system decreases two quantitative stages or so when the efficient structure and optimizing algorithm of linear-phase FIR filter are adopted.
