Abstract: Orthogonal Frequency Division Multiplexing (OFDM) has established itself as a very appealing technique for high-rate data transmission over dispersive channels. The main disadvantage of OFDM is that the signal exhibits Gaussian-like time-domain waveform with high Peak-to-Average Power Ratio, which limits the efficiency of the transmitter amplifier and degrades the received signal to noise ratio. Companding technique can be employed to mitigate quantization noise and the Peak-to-Average-Power ratio of OFDM system. In this paper, symbol error rate of the companded OFDM systems is investigated. The performances of the systems with and without companding are compared.
