Communications Performance Enhancement and Analysis of Diversity Techniques for Broadband Wireless

Abstract

 In this section, we can obtain a multiple-input multiple-output (MIMO) technique combining transmit antenna Selection and receiver maximal-ratio combining. In this technique, a single transmit antenna, which increases the received signal power at the receiver, is selected for non coded transmission. When we are using receiving diversity scheme then we found MRC Technique is given better result and for transmit diversity we found transmit beam forming is better. After an overall conclusion, we obtain that MRC at receiving end is best overall. The results output provides us that the less Bit error rate as we increase the antenna configuration. It is shown that the MRC scheme outperforms some more different space-time coding of the same efficiency.
