摘要：High peak to average power ratio (PAPR) is a very serious drawback in Orthogonal Frequency Division Multiplexing (OFDM). Multiple transmit and receive antennas can be used to form multiple-input multiple-output (MIMO) channels to increase the ca pacity and data rate. We propose the novel approach which is reduce PAPR and Computational complexity without any distortion based on clipped OFDM. In these technique the phase sequence multiplication before perform FFT operation by using PN sequence generator and second phase sequence multiplication are the invert version of PN sequence generator. The performance of Space-Frequency (SF) block coding for MIMO OFDM along with different equalizers is also analyzed. Bit Error Ra te (BER) analysis is presented using different equalizers and then optimum equalization method is suggested .We show the practical aspect of propose scheme in MATLAB environment
