| Abstract | ||
| Wireless communication systems play an important role in our life and society. In this paper, the different types of wireless communication systems Single Input-Single Output (SISO), Single Input-Multiple Output (SIMO), Multiple Input-Single Output (MISO), and Multiple Input- Multiple Output (MIMO) were described and compared from capacity and Bit Error Rate (BER) point of view. It was found that the capacity of MIMO communication system is better than other systems. An additional improvement was obtained by using Space Time Coding (STC). Space Time Block Code (STBC) improve the BER of MIMO by (78,6%), and Space Time Trellis Code (STTC) improve the (BER) at the receiver side by (91.37%). Also the use of Artificial Neural Networks (ANN) improve the STTC MIMO communication system by 54.16%. All measurement are done at SNR = 8dB. Using MATLAB version 2013a. | ||
