## ABSTRACT The performance system with variableβpower adaptive modulation over Nakagamiβ__m__ fading channels is presented. The optimum switching thresholds for attaining maximum spectrum efficiency (SE) subject to a target bit error rate (BER) and an average power constraint are derived. The exis
