This paper theoretically analyzed the performance of the RAKE combining(in the time domain), maximal ratio combining(in the spatial domain), and two-dimensional RAKE combining(in the spatial and time domains)techniques for multipath fading environments, where multipath waves are distributed in the spatial and time domains.The analysis was based on a diversity combining technique that employed the eigenvalues of the covariance matrix between branch signals.It was found that the performance of the fading mitigation was normalized by the beamwidth of an array antenna, for various parameters such as the number of antenna elements, angular spread, and angle of arrival.
