Abstract :
This paper presents feasibility studies for the implementation of a multi-standard, multimode RF front-end enabling utilization of location based services (LBS) in a mobile handset using A-GPS system with GSM and UMTS support. A short description of the proposed system architecture is presented. The setup is proven based on the system simulations using Matlab. The influence of gain compression, wideband noise and reciprocal mixing on the system performance due to a full-duplex interferer is described. The analysis is extended for intermodulation test cases in a mobile environment. Feasibility analysis is confirmed with measurements of a GPS/Galileo/UMTS/CDMA2000/GSM reconfigurable front-end implemented in 130nm CMOS technology.
