4G receiver: Modeling of a multi-standard transceiver and study of algorithm control

This Article is reporting implementation and verification of the base-band equivalent RF models which is used in link level simulations with demodulator model such as Nokia's Wireless Modem (NWM) and ST Ericsson modem link simulators. The model represents the chain of filtering, amplification and is responsible for the realization of the selectivity of the canal. The transceiver is constituted by the following models: · AFE (Analogical Front End) · DFE (Digital Front-End) · AGC (adaptive gains control).
