Analysis of the Comparison of OFDM and WPM in the Communication System

The fundamental theories of OFDM and WPM have many similarities in their functions and performance but there are some significant differences which give two systems to be distinctive. OFDM signals only overlap in the frequency domain while the wavelet signals overlap in both time and frequency domain. In the paper, WPM instead of conventional OFDM is used in WIMAX system. The simulation results show the WPM on WIMAX has lower bit error rate compare to conventional OFDM WIMAX.
