Transmit simulation and receive optimizations for 802.11b networks

The simulation presented in this paper provides an implementation of a full simulated transmit chain from packet encoding through base band modulation for the 802.11b wireless networking standard. This forward transmit chain is coupled with a physical channel simulation that can introduce a number of different channel effects to simulate interference caused in the real world. Packets which the transmit simulation produces can be sent to a receive simulation to test design parameters or can be modulated and sent to 802.11b hardware to test hardware implementation. Using former procedure, this paper also evaluates implementations of a Phase lock loop used to track Frequency Doppler and a Time Tracking Loop used to track Code Doppler under various Signal to Noise levels. The results from these simulations can be used to optimize various receive parameters and algorithms.
