Abstract :
Hybrid forwarding scheme for wireless relaying is able to adapt to changing channel conditions by switching between amplify & forward and decode & forward, so as to decrease the energy consumption, time delay and complexity in practical system. The strategy evaluates the SNR at the relay and set it as the selection criteria. Although the BER performance for hybrid forwarding has been analyzed before, very little research has been focused on outage probability. In this paper, we analyze the outage probability performance the introduced strategy and derive a closed-form of analytical solution of outage probability using hybrid forwarding in wireless relaying system.
