Abstract:
    The invention relates to a user signal wave direction evaluate method of array antenna MC-CDMA system, wherein it comprises that: first, the sub carrier wave de-spread match filter connected to the array antenna separates the user at each sub carrier wave, to obtain the output vector of sub carrier wave on match filter; then processing frequency domain summation on each match filter, to obtain output vector sum of all antenna match filters; then based on sample of vector sum, obtaining the sample evaluated value of output vector relative to the covariance matrix; then processing characteristic decomposition on covariance matrix, to obtain the evaluated value of main characteristic vector of covariance matrix; at last, based on the spatial spectrum function of main characteristic vector, searching the spectrum peak of spatial spectrum function to obtain the evaluated value of user signal wave direction.
