Abstract
A method of achieving diversity in a multiple-input-multiple-output (MIMO) communication system. The MIMO communication system has a lower number of receiving antennas compared to the number of transmitting antennas. In the MIMO communication system, selection diversity is achieved by using a switch that selectively chooses a receiver antenna based on a signal to noise ratio of the signal captured by the receiving antenna. Alternatively, the signals that are received by the respective receiving antennas are combined in order to achieve combination diversity.
