High data rate transmission in multi-service code division multiple access wireless communication systems

by Sun, Songsong

The first and second generation wireless systems are mainly designed for voice service. With the expanding usage of Intemet, the demand for wireless data service has been the driving force for the design and development of third generation wireless systerns, which are required to suppoa voice, as well as circuit and packet data services. The code division multiple access (CDMA) technique has been accepted as the multiple access scheme for the third generation wireless standards dl over the world. This Ph.D. thesis addresses the issues of high data rate transmission in multi-service CDMA wireless communication systems. The study involves the design and analysis of efficient access schemes, fast chip synchronizers, radio link protocols and cal1 admission control policies, system capacity analysis, optimal transmitted power allocation, as well as the optimization of the signal-to-interference ratio assignment.
