Cooperative Relaying Systems represent a promising solution for future wireless communications. In this paper simple cooperative relaying strategies are proposed in order to improve the performance of a WiMAX network, overcoming the drawbacks of a Non-Line-Of-Sight (NLOS) propagation. The cooperative schemes proposed combine the Amplify and Forward (AAF) and the Decode and Forward (DAF) algorithm with Delay Diversity (DD) and Cyclic Delay Diversity (CDD) techniques, in order to exploit the features of the wireless communication channel. We investigated the pros and cons of each scheme, comparing the assumptions which are required and the simulation results with respect to two cooperative implementations of the Alamouti scheme.

Abstract
Cooperative Relaying Systems represent a promising solution for future wireless communications. In this paper simple cooperative relaying strategies are proposed in order to improve the performance of a WiMAX network, overcoming the drawbacks of a Non-Line-Of-Sight (NLOS) propagation. The cooperative schemes proposed combine the Amplify and Forward (AAF) and the Decode and Forward (DAF) algorithm with Delay Diversity (DD) and Cyclic Delay Diversity (CDD) techniques, in order to exploit the features of the wireless communication channel. We investigated the pros and cons of each scheme, comparing the assumptions which are required and the simulation results with respect to two cooperative implementations of the Alamouti scheme.File | Dimensione | Formato | |
