书籍 HSDPAHSUPA+for+UMTS+High+Speed+Radio+Access
The first Third Generation Partnership Project (3GPP) Wideband Code Division
Multiple Access (WCDMA) networks were launched during 2002. By the end of 2005
there were 100 open WCDMA networks and a total of over 150 operators having
frequency licenses for WCDMA operation. Currently, the WCDMA network ...
书籍 Interference+Mitigation+Techniques
This research work aims at eliminating the off-chip RF SAW filters from fre-
quency division duplexed (FDD) receivers. In the first approach, a monolithic passive
RF filter was constructed using on-chip capacitors and bondwire inductors. The bond-
wire characteristics were studied in details and the ...
书籍 SAE and the Evolved Packet Core
The outcome of the 3GPP SAE (system architecture evolution) technical study
and specification work is a set of standards that specifies the evolution of the
packet core network for GSM/GPRS and WCDMA/HSPA to an all-IP architec-
ture and enables a feature-rich ‘common packet core’ for radio accesse ...
书籍 WCDMA for UMTS HSPA Evolution and LTE
Second-generation telecommunication systems, such as the Global System for Mobile
Communications (GSM), enabled voice traffic to go wireless: the number of mobile phones
exceeds the number of landline phones and the mobile phone penetration is approaching
100% in several markets. The data-handling c ...
书籍 Wideband+TDD
This book is an outgrowth of the pioneering development work done by InterDigital Com-
munication Corporation in 3rd Generation TDD WCDMA Technology. Many engineers
and managers were involved in this development, which spanned a wide range of tech-
nology areas, including system architecture, radio ...
