Abstract: In this paper an outdoor channel model known as SUI Channel with Partial Transmit Sequence is used to reduce PAPR which is major drawback in OFDM system. This method has better transmission performance. It can transmit high data rate signals.The performances in terms of bit error rate (BER) and reduction of PAPR has been investigated by using SUI5 channel model. BPSK and PAM modulation techniques are used for analysing BER performance. The proposed frame work can be simulated in MATLAB R2012a.

Keywords: SUI channel, Partial transmit sequence, BER.
