An emission/reception chain modelling of the WiMAX access network

چکیده
This 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.

The computer industry has defined the IEEE 802.16 family of standards that will enable mobile devices to access a broadband network as an alternative to digital subscriber line technology. As the mobile devices join and leave a network, security measures must be taken to ensure the safety of the network against unauthorized usage by encryption and group key management. IEEE 802.16e uses Multica...
متن کاملSeamless Vertical Handover in WiFi and WiMAX Networks using RSS and Motion Detection: An Investigation
In this paper, we propose a decision making algorithm for seamless vertical handover between WiFi hotspots and an overlay WiMAX network. The inputs to the algorithm are the WiFi received signal strength (RSS) and estimated end-to-end TCP handover latency. Simulation of the algorithm using Matlab ® reveals that the distance from the WiFi reception boundary at which handover must be initiated if ...
متن کاملCoordination of green supply chain network, considering uncertain demand and stochastic CO2 emission level
Many supply chain problems involve optimization of various conflicting objectives. This paper formulates a green supply chain network throughout a two-stage mixed integer linear problem with uncertain demand and stochastic environmental respects level. The first objective function of the proposed model considers minimization of supply chain costs while the second objective function minimizes CO...
