A comparitive analysis of Army waveforms & commercial wireless protocols at the PHY/MAC layers

This paper will present a comparison of the basic resource definition in an OFDMA MAC/PHY layers for WiMAX and the TDMA/OFDM MAC/PHY. The majority of current radios in development for the US Army use TDMA/OFDM. This comparison will be conducted by defining and discussing the basic unit of system resource, e.g. the ¿slot¿. Following the protocol comparison, some simulation results comparing the performance of both systems will be provided.
