Original Kurzfassung:
Multi-mode operation of wireless transceivers has become a major issue due to the ongoing evolution of 2G to 3G and beyond mobile communication standards. As a result the cellular market is confronted with the challenge of a broad diversity of communication standards. This paper discusses the design of an adaptive wireless receiver for multi-mode operation and power efficiency by sharing digital signal processing stages for all operation modes and adapting them for minimum power consumption with respect to the channel selection requirements of the main cellular communication standards (GSM/EDGE, CDMA2000, and W-CDMA/HSDPA) and satellite navigation systems (Galileo). The proposed approach is verified by simulations exhibiting an error-vector-magnitude (EVM) of 2.9 % in W- CDMA while the estimated power consumption can be reduced by 62 % versus full featured mode.
