System-Level Time-Domain Behavioral Modeling for a Mobile WiMax Transceiver

The time-domain baseband equivalent model for a mobile WiMax, IEEE 802.16e RF transceiver has been addressed in this paper. The baseband equivalent model is built up based on complex signals and spectrum. Nonlinearity up to the fifth order harmonics is considered, and noise characteristics are modeled in time domain for...
