Abstract :
A generalized spatial correlation approximation based on pulse sampling in angle domain is proposed. The new scheme can been used to evaluate the spatial correlation of received signals under arbitrary scattering scenarios. Different sampling pulses are compared which shows the raised-Cosine pulse is better than others. Numerical simulation results demonstrate that the approximate method has more high accuracy and lower complexity comparing with other traditional approximate methods.
