Abstract
Today trade wireless communication systems are wanted to equip reliable communication and bigger data rates. Two considerable challenges in system design are the restricted fading and spectrum due to multipath components in the wireless system. Multiple transmission and reception can be used to form (MIMO) multiple input multiple output channels to raise the data rate and capacity. The advantages of utilizing multiple antennas are to get reliable performance and a higher data rate. In this paper, an attempt is made to design and simulate SISO, SIMO, MISO and MIMO systems. We have analyzed and compared the performance of these systems based on SNR and channel capacity in a different number of an antenna. The effect of the number of an antenna (4, 8, and 16) on the channel capacity over a range of SNR (0-30db) for the systems is examined. The system performance is simulated in Matlab. The results of the simulation show that as significant improvement in the capacity of systems reached dramatically to 214 (bits / Hz / Sec) when SNR = 30 and (16X16) MIMO is used.
