Increasing a number of receive antennas in STBC-MIMO system yielded increasely spatial diversity gaining. Furthermore, increasing a number of transmit antennas created better spatially multiplexing gaining. However, coding rate created decreasing system performance, higher coding rate yielded worse performance than lower code rate. Using monte-carlo method, this paper simulated the system performance that enclosed many variations these are a number of transmit antennas (3, 4 antennas), a number of receive antennas (2,3,4 antennas) and coding rate (½, ¾).
