General interference analysis of M-QAM and M-PSK wireless communications

This work includes an accurate and general technique, which has been developed to analyze the symbol-error-rate (SER) of coherent M -Quadrature Amplitude Modulation (QAM) and Phase Shift Keying (PSK) schemes for various conditions of the transmission. A calculation scheme has been presented dealing with Additive White Gaussian Noise and different fading effects influencing the analyzed M-ary QAM or PSK signals. Furthermore, the authors have considered the effects of multiple interference signals embedded into a stochastic model having numerous parameters, which can be assumed as random variables with adjustable distributions. The resulted M -QAM and M -PSK SER expressions have been extended for multi-carrier transmission based on the analytical calculation of the stochastic interference model.
