Modeling Multpath In 802.11 Systems
In this paper we’ll detail one of these models, a multipath model, that will enable designers to compare the performance of 802.11, 802.11b, and 802.11a system designs. The model presented here is statistically verified using a Simulink/Matlab platform. The effect of delay spread for these transceiver waveforms using the multipath channel model will be presented.… Continue Reading
