A method of Symbol Error Ratio(SER) computation for cross Quadrature Amplitude Modulation(QAM) signals is given.The constellation is divided into different regions based on decision boundaries according to the characteristics of cross QAM.The general theoretical bounds of SER for the cross QAM signals over Additive White Gaussian Noise(AWGN) channel and Rayleigh fading channel are given.Analysis and simulation results demonstrate that the theoretical bound offers an accurate criterion for SER of cross QAM.
