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

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.       
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. 		      

Requirements for completing the course
Exam (5 cr). Possibility for up to 7 cr by completing a Matlab project.
