Cross-layer design for throughput improvement in wireless communications

For a TCP/IP based next generation wireless networks, a conventional layered design is not optimum because it is not considering mobile propagation characteristics. Cross-layer design is the one of the most efficient alternate networks architectures. In order to improve the throughput, Hybrid SMD (symbol mapping diversity) technique has been proposed. Hybrid SMD technique is based on cross-layer design over wired communication channel. It is necessary to have a suitable method over wireless communication channel. We propose a novel SMD method for this purpose.
