Abstract :
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 amplifiers and mixers. The time-domain phase noise is also implemented as part of PLL-based local oscillators. The non-ideal parameters, DNL and INL, are defined to describe non-linearity of ADC and DAC. With this behavioral models implemented on Matlab/Simulink environment, the performance of a complete mobile WiMax transceiver can be evaluated and predicted before an actual hardware design
