| Abstract: | Based on the IEEE802.11a standard, this paper analyzes the impact of physical layer coding rate, modulation and the frame length of the MAC layer on throughput performance, A MAC and PHY cross-layer algorithm is proposed. Simulation results show that the proposed cross-layer transmission scheme could remarkably enhance the system throughput rate |
