Abstract
A gain adjustment apparatus, a gain adjustment method, and a tangible machine-readable medium thereof for a multiple input multiple output (MIMO) wireless communication system are provided. The MIMO wireless communication system comprises source antennas, destination antennas, relay stations (RSs) and a relay transmission power limit value. The gain adjustment method comprises the following steps: adjusting the gain of one single RS according to a gain calculation; multiplying the gains of other relay stations by a scaling value for adjustment. According to aforesaid method, the present invention can increase the system capacity of the MIMO wireless communication system.
