Performance Analysis of Different Diversity Combining Techniques in Cooperative Wireless Communication System

Diversity is a powerful communication receiver technique that provides wireless link improvement at relatively low cost. This paper develops a general framework for diversity combining techniques in cooperative wireless communication system. This article, a synopsis to cover different approaches to exploiting the benefits of diversity and multihop communication via relays, such as solution for radio range extension in mobile and wireless broadband cellular network. Relaying is presented as a means to reduce infrastructure deployment costs. It is also shown that through the exploiting of spatial diversity, multihop relaying can enhance capacity in cellular network. We wish to emphasize that while this articles focuses on fixed relays, many of the concept presented can also be applied to system with moving relays.
