Executive Summary

Recently, Orthogonal Frequency Division Multiplexing (OFDM), as a multi-carrier, and a single carrier transmission systems are used widely in the communications industrial systems. Each one of these two techniques has their own advantages and disadvantages. To maintain a high data rate, OFDM is preferred over the single-carrier transmission system due to several shortages like, complexity of equalizing that increases proportionally with the data rate. To overcome this problem, OFDM is used as a transmission system with much better Bet Error Rate (BER) performance. Peak-to-Average-Power Ratio (PAPR) is major drawback of using OFDM but users' can deal with it using clipping and filtering as a power reduction technique.
