Advanced signal processing techniques for interference suppression in CDMA communications.

摘要

The ever increasing demand for performance and capacity in wireless systems has motivated the development of advanced signal processing techniques for signal reception. In this work, we develop, analyze, and simulate several signal processing techniques for the mitigation of interference in code-division multiple-access (CDMA) systems. In particular, we present our contributions to five areas: turbo receivers, space-time processing, low-complexity blind adaptive multiuser detection, transmitter optimization for blind and group-blind multiuser detection, and transmitter precoding. In each case, we will see that the algorithms presented offer significant advantages over existing techniques. We also present suggestions for future research.
