Performance Analysis of M-Ary PSK OWDM on Wireless Communication Systems

This paper deals with the performance analysis of M-ary phase shift keying (PSK) based on wavelet packet modulation, known as orthogonal wavelet division multiplexing (OWDM). The proposed modulation scheme is implemented by utilizing a uniform filter bank both at the transmitter and the receiver to provide high modulation performance with improved bandwidth efficiency which is almost required for wireless communication systems. To demonstrate its performance, conventional M-ary PSK and orthogonal frequency division multiplexing (OFDM) systems are also evaluated and analyzed under Rayleigh distributed frequency selective fading channel and with the presence of additive white Gaussian noise (AWGN). From the performance result, it is shown that M-ary PSK with the implementation of 64 subcarrier OWDM modulation scheme outperforms the OFDM and the conventional ones where it provides BER performance with the value of 1×10
