An analytical comparison among adaptive modulation, adaptive FEC, adaptive ARQ and hybrid systems for wireless ATM networks

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.
