Abstract

An exact and general performance analysis has been introduced for M-QAM modulation in terms of bit error ratio (BER) and transmission rate assuming gray mapping. BER expressions have been derived for different fading channel types (Rayleigh, Rice and Nakagami). The analyzed transmission considers OFDM interference, which is influenced by Rayleigh fading channel. During the calculation, the spectral shapes of the victim and interfering signals are also considered. The BER expressions have also been applied for LTE, giving a tool for the evaluation of LTE physical layer performance in adjacent channel interference scenarios.
