Abstract :
We propose a new approximate correlation formulation when the AoA distribution is uniform distribution or other uniform-distribution-like AoA scenarios. The approximation can speed up the correlation calculation compared to numerical method and enhance the accuracy compared to the previous works, which is beneficial for the judgement of channel condition of two MIMO antennas.
