Abstract :
We propose coded wavelet based OFDM (WOFDM) with MLC/MSD scheme based on capacity rule. BER performances of coded WOFDM systems with MLC/MSD are investigated on AWGN and Rayleigh fading channels respectively. In the MLC scheme, BCH codes of length 127 are employed as component codes. Different component code rates are used, and their performances are compared on different channels. Results show that the capacity rule works well in our proposed systems. The performances are different when codes rates do not comply with the capacity rule in different degree.
