Title
Turbo-Coded HARQ with Switchable Relaying Mechanism in Single Hop Cooperative Wireless System
Abstract
Cooperative relaying has recently received significant attention due to its diversity gain, higher QoS, power savings, extended coverage and improved BER as compared to conventional SISO systems. For further improvement in the system performance, Hybrid ARQ proves itself as effective transmission strategy. Exploiting the retransmission nature of Hybrid ARQ, this paper proposes Switchable Relaying Mechanism (SRM) to be used with Turbo codes in a single hop Cooperative System. According to channel conditions, SRM will let the relay to switch its relaying protocol between AAF and DAF. Moreover, retransmission mechanism at destination guarantees improvement of an overall system performance. The proposed Hybrid ARQ-SRM scheme when used with Turbo codes has shown better BER performance as compared to conventional cooperative systems.
