Abstract:: On the basis of N-Nakagami fading channels，the average symbol error probability ( ASEP) andoutage probability ( OP) of mobile wireless sensor network system employing switch-and-stay combining( SSC) and selection combining ( SC) are investigated in this paper. Based on the moment generating function(MGF) approach,the exact ASEP expressions are derived for several modulation schemes，including phaseshift keying ( PSK ),quadrature amplitude modulation ( QAM ),and pulse amplitude modulation ( PAM).The exact closed-form OP expressions are also presented. Then the ASEP and OP performance under differentconditions is evaluated through numerical simulations,and the accuracy of the analytical results is verified.The simulation results showed that: the ASEP and OP performance is improved with the diversity branches andthe fading coefficient increased ,while the fading factor decreased.
