Abstract :
This paper considers different adaptive modulation techniques for flat fading channels when turbo codes are used as channel codes. The optimal adaptive TuCM scheme is determined subject to various system constraints. It is shown that adapting both the turbo-encoder and the transmit power achieves a performance within 3 dB of the fading channel capacity
