Abstract: |
This paper describes the operation procedure of IEEE802.16d -based transmitter and receiver, analyses the basic principle of the system physical layer, and on this base, with the LahVIEW system simulation software designs a typical WirelessMAN - OFDM system simulation model and framework. The system simulation model and framework may help to deeply research and discuss the WirelessMAN - OFDM system and is very important for the optimized design of WiMAX system and also shortening the system developing cycle. |
