Another Look at Multibranch Switched Diversity Systems

We propose an alternative simpler implementation of generalized switch and stay combining (GSSC) receiver, which utilizes only one switching circuit and includes the classic dual SSC as a special case. Its performance is evaluated over Nakagami-m fading channels leading in closed-form expressions for the average symbol error probability. Moreover, for the case of non identical branches, the optimum threshold is accurately approximated in closed-form, avoiding the use of complicated numerical methods
