Multi-standard simulation of WLAN/UMTS/GSM transceivers for analog front-end validation and design

A system-level multi-standard simulator is set up to help the architectural and circuit-level design of RF front-ends whose building blocks are meant to be shared between transceiver chains of different standards. The simulator distinguishes the baseband digital processing and analog processing. Non idealities of analog blocks are modeled in detail taking into account the nonlinearities, band limitation, losses, thermal noise, etc. The simulator provides all classical compliance tests (sensitivity, maximum input, adjacent channel rejection, pureness of modulation, spectral profile, etc.) and can also assess the joint effect of high-level analog design parameters on the performance of the transmission chain at bit- or packet- level.
