Section 4 then addresses the issue of maximizing data throughput while .. where the final expectation is taken over the pdf of an individual eigenvalue, found by marginalizing.
Antenna diversity, also known as space diversity or spatial diversity, is any one of several wireless diversity schemes that uses two or more antennas to improve the quality and reliability of a wireless link. Often, especially in urban and indoor environments, there is no clear line-of-sight (LOS) between transmitter and
20 Dec 2017 Full-text (PDF) | It is well-known that using multiple antennas provides a substantial capacity and diversity increase for wireless communication systems. A multi-input multi-output (MIMO) technique that utilizes the channel knowledge both at the transmitter and the receiver is known as beamformin
