Performance Evaluation of Decode-and-Forward Relaying for Cellular Communication Network

In this paper, the performance of decode –and-forward relaying over multiple fading channels is been analyzed. Here at first overviewed traditional relaying techniques and compared it with coded cooperative relaying. BER performance the different schemes are analyzed and the results shows that coded cooperative relaying give better performance in terms of BER analysis. A new technique called network Coded cooperative relaying is introduced, analyzed the new scheme in terms of blocking probability and spectral efficiency. Diversity technique enhances link quality and increasing network capacity. Network coding achieves higher diversity order than other conventional relaying schemes. And the result shows that network coded cooperative relaying outperforms conventional relaying and non-relaying scheme. For improved performance for cell edge users also, location of relay based on distance measurement is also performed. Due to this cell center users also give better performance similar to cell edge users.
