Threshold-Based Relay Selection For Cooperative Wireless Network

Abstract

Cooperative communication plays a vital role in the wireless domain recently due to its numerous benefits such as coverage extension, improvement in spectral efficiency, and
throughput by increasing the complexity of the system. Furthermore, security becomes a key issue for implementing a cooperative communication system.

In this thesis, the complexity is reduced by employing differential modulation as they do not require complete channel state information (CSI). Different threshold-based relay selection schemes are also proposed to reduce complexity. Furthermore, the security issue in the cooperative wireless network is addressed by enhancing the physical layer security using the proposed double threshold-based optimal relay selection scheme.
