Handover considerations in VCO design for multistandard wireless receiver

This paper analyses handover scenario used in 3G standard and results are used to design and implement a reconfigurable voltage controlled oscillator (VCO) for multistandard wireless receiver. The third-generation (3G) standard has introduced hybrid wireless network for better use of resources. The typical example of hybrid network is integration of radio access technologies such as Wideband Code Division Multiple-Access (W-CDMA) and global system for mobile (GSM). In such hybrid systems handover analysis is mainly used to extract general requirements and specifications for front-end design. In 3G different handover types are used such as 3G to 3G, 2G to 3G and 3G to 2G, to provide better service to users. The static handover analysis is performed to support design and implementation of a reconfigurable, compact, multi-standard compatible VCO based on switch architecture
