Abstract:

By analyzing channel model mechanism of Markov stochastic process, the channel modeling scheme of 802.11n is studied and the simulation module of 802.11n channel model D is implemented in NS2 software environment based on corresponding Look Up Table(LUT) which includes Channel Capacity(CC), Packet Error Rate(PER) and Signal to Noise Ratio(SNR). It verifies the accuracy of this module through comparing simulation results with TGn standard model. The module provides efficient physical layer channel simulation foundation for the research and improvement of the 802.11n protocol.

Key words: 802.11n D channel model, Markov chain, Channel Capacity(CC), Packet Error Rate(PER)
