Performance Analysis of High QAM OFDM System Over Frequency Selective Time-Varying Fading Channel
Overview This paper considers the performance degradation of a high QAM orthogonal frequency division multiplexing (OFDM) system over frequency selective time-varying fading channels. The time variation of the channel during one OFDM frame destroys the orthogonality of different sub-carriers and generates power leakage among the subcarriers, known as Inter-Carrier Interference (ICI). The statistics of the ICI for M-QAM systems are shown to be non-Gaussian distributed.
