An emission/reception chain modelling of the WiMAX access network

International audienceThis work describes the simulation under the Simulink environment of Matlab of an IEEE802.16 complete transmitter/receiver chain. Because of its superior performance the WirelessMAN OFDM 256 PHY layer is the most implemented in WiMAX compliant devices. The first part of the paper concerns the validation of a transmitter model using that PHY layer while the second part of the article deals with a complete transmitter/receiver model proposed. An example with a 20 MHz channel using adaptive modulation is considered and analyzed. This model takes into account several constraints and problem of the standard translation: reducing ambiguity in the standard and providing a reference for compliance testing
