Non-binary spread-spectrum multiple-access communications / Derek Paul Rogers.

Rogers, D. P. January 1995 (has links)
Bibliography: leaves 181-201. / ix, 201 leaves : ill. ; 30 cm. / Title page, contents and abstract only. The complete thesis in print form is available from the University Library. / This thesis investigates non-binary spread-spectrum multiple-access communications. The research considers wide generation techniques, system performance, how performance is influenced by the different properties of the codes, and how those properties relate to the code generation technqiue. The research refines the code design philosophy and investigates this by developing a novel code generation technique. / Thesis (Ph.D.)--University of Adelaide, Dept. of Electrical and Electronic Engineering, 1995?

Predictive power control in CDMA systems

Kurniawan, Adit January 2003 (has links)
This study is aimed at solving several important problems relating to power control in CDMA systems. Our focus is on the mobile to basestation (reverse) link. In this study, we propose a new SIR estimator for CDMA systems, using an auxiliary spreading sequence method. The proposed SIR estimator is employed at the basestation to estimate the SIR, which serves as a control parameter in the power control algorithm. The effects of system parameters (step size, power-update rate, feedback delay, SIR measurement error, and command error) on the bit error rate (BER) performance of power control are investigated. Feedback delay is found to be the most critical parameter that causes a serious problem in the loop. To solve this problem, we propose to use a channel prediction technique at the basestation. To further improve the performance of power control, we then propose to use a diversity reception technique using antenna arrays at the basestation. We show that this combination allows solving the problems linked to the use of power control in a real system affected by multiple access interference under fading conditions. / thesis (PhD)--University of South Australia, 2003.
