Abstract :
Several adaptive transmission schemes have been proposed to improve the performance of wireless networks, with adaptive modulation and adaptive error control receiving a lot of attention in the last years. We compare the performances of adaptive forward error correction (FEC), adaptive automatic repeat request (ARQ) and adaptive modulation schemes. We have analysed a hybrid scheme, that uses adaptive FEC together with adaptive modulation, to improve the performance and decrease the complexity of the error correction code.
