摘要：
In this paper, the influences of iterations and the length of the interleaver on the performance of turbo codes in regions of low signal to noise ratio over Rayleigh fading channels are studied on the wavelet based orthogonal frequency division multiplexing (WOFDM). The results show that to improve the performance of turbo codes in WOFDM systems you have two ways to choose: increase the iteration number or enlarge the length of your interleaver. But, both the ways can bring side effects to your systems, it is also the case on coded OFDM systems. According to the demand of concrete system there must be a trade-off.
