In this configuration, the antenna arrays at the BS are distributed, and each antenna uses a separate local oscillator, that is, [N.sub.0] = M.This is known as non-synchronous operation at the base station, and the base station antennas have independent phase noise processes for all m = 1,...,M [20, 27].
