Abstract：Capacity is an important indicator in communication systems performance.This paper researches on the mean value of the capacity and the variance in Orthogonal Frequency Division Multiplexing/Offset Quadrature Amplitude Modulation(OFDM/OQAM) system under condition of multipath Rayleigh-Fading channels,obtains the probability density function (PDF) of Rayleigh channels model,and deduces the alliance of probability density function in two random relevance Rayleigh channels.The paper gets the mathematical expression about the mean and variance OFDM/OQAM system capacity in multipath Rayleigh-Fading channels,where the function of the parameter is related to the number of the subcarriers of an OFDM/OQAM system,the signal to noise ratio(SNR) and the number of multipath.The result shows that the systems mean is proportional to SNR and inverse proportional to the number of the subcarriers;the systems variance is defined by SNR and the number of multipath.
