The adaptive modulation and coding can provide robust and spectrally efficient transmission over generalized ¿-¿ (or generalized gamma) wireless fading channels. The key idea of our proposal is to transmit the low-density parity-check (LDPC) encoded sequence over the generalized fading channel, feedback the channel state information of by an RF feedback channel, and adapt the powers and rates of so that the channel capacity is maximized. The optimal power adaptation policy maximizing the channel capacity is derived. We show that deep fades can be tolerated with proposed scheme.
