MIMO (Multiple Input Multiple) technology which uses multiple antennas at both transmitter and receiver at physical layer is widely known as an effective and efficient approach in order to achieve high reliability and high spectrum efficiency. Due to diversity gain in MIMO systems, the effect of multiple path fading on the transmitted data can be reduced. This paper presents the impact of transmit antenna diversity using STBC (Space Time Block Coding) and receive antenna diversity using MRC (Maximal Ratio Combining) on performance in MIMO communications. In addition, a simulation tool with graphical user interface (GUI) by using Matlab is built for evaluating the performance. In this tool, the parameters such as packet length, number of transmitted packet, modulation, channel model, and number of transmit/receive antennae can be changed easily on the interface of the tool.
