The channel capacity is improved by MIMO (Multiple Input Multiple Output) increasing the number of transmit and receive antennas. However, it is difficult for a receiver to decode symbols when the rank of a MIMO channel is less than the number of transmitted antennas. Thus, rank adaptation has been proposed to control the number of transmitted streams in accordance with propagation environments. Conventional...
We investigate an adaptive spatial multiplexing order based on an increase in channel capacity. The channel capacity of a MIMO (Multiple Input Multiple Output) system increases linearly as the number of transmit antennas. However, the throughput cannot increase in a poor channel environment as the number of antennas. The spatial multiplexing order is then required to be controlled according to channel...
