Abstract :
In this paper, we first provide an overview of the woven convolutional codes (WCC) and an iterative decoding scheme for WCC. Then we present a new coded wavelet based multicarrier modulation (WMCM) systems scheme by using WCC as channel coding scheme. Using simulation analysis, we lastly shown the bit error rate (BER) performance of WCC coded WMCM scheme. The simulation results show that increasing the number of decoding iterations of WCC-WMCM can not bring so much coding gain in the low regions of Eb/No. But in the middle to high regions of Eb/No, increasing the number of decoding iterations can greatly improve the performance of WCC-WMCM. We also get that the frame- length will also impact the system performance.
