In today's wireless communication, the efficient utilization of resources is the main concentration of engineers and spectrum of the most significant resources. So the aim is to exploit the bandwidth in a competent manner. From the report of FCC it is known that the 70% of spectrum occupied by several mobile operators is not fully utilized that leaded to motive new developments of spectrum efficient communication technologies. Therefore, the present work, investigates the performances of several systems such as SISO, MISO and MIMO OFDM and wavelet based OFDM systems to reflect the expected improvements can be made in terms of BER versus SNR and PAPR in Multipath Rayleigh fading channel. The performance analysis over the modulation impact using BPSK, 4QAM, 16QAM and 64QAM are discussed.
