Abstract
Based on cross-layer design, an optimization method was proposed, which combined the adaptive modulation and coding with symbol rate at the physical layer, and the packet size and sub-packet number at the data link layer. The parameters were jointly optimized to maximize the MIMO system throughput in the Rayleigh fading channel. Numerical results reveal that the optimization method can be adapted to the time varying wireless channel and greatly improve the throughput compared with separate layer design. Besides, under prescribed error performance constraint, the larger the maximum number of transmissions, the higher the throughput. A small number of transmissions can offer a desirable delay-throughput tradeoff in practice.
