## ABSTRACT The performance system with variableโpower adaptive modulation over Nakagamiโ__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
