Objectives

The course focuses on the principles and theory of spread spectrum communications with emphasis on CDMA. Issues to be covered include principles of SS techniques, spreading codes, code acquisition, code tracking and performance analysis of single- and multi-user detection in various channel conditions. Applications in WCDMA and positioning systems.

Content

Content	Core content	Complementary knowledge	Specialist knowledge
1.	Basics of spread spectrum techniques, spreading, multiple access, DS-CDMA basics, multi-access interference.
2.	Spreading sequences, shift registers, spreading code families and their properties (m-sequences, Gold, Kasami, orthogonal codes).
3.	Code acquisition and tracking, search strategies, mean acquisition time analysis. Multipath propagation and impact on code synchronization; Feedback and feedforward code tracking structures
4.	Conventional single-user detection, performance analysis in AWGN, fading and single/multi-user channels, gaussian approximations, diversity reception, rake receiver, near-far resistance and multiuser efficiency.
5.	Optimal multi-user detection: decision strategies and performance analysis, optimal near-far resistance. Sub-optimum multi-user detection: decorrelating and MMSE detection, iterative detection, parallel and successice interference cancellation.
6.	Satellite-based positioning systems; focus on CDMA satellite navigation; acquisition and tracking - specific structures for navigation; challenges in satellite navigation; differences with CDMA communication systems.	Overview of satellite navigation systems nowadays (GPS, Galileo, GLONASS, Compass-Beidou, etc.)
