Suitable for postgraduate studies
Will not be lectured year 2014-2015
Person responsible
Elena-Simona Lohan, Markku Renfors
Requirements
Exam (5 cr). Possibility for up to 7 cr by completing a Matlab project.
Completion parts must belong to the same implementation
Learning Outcomes
The course focuses on the principles and theory of spread spectrum communications with emphasis on CDMA. After the course, a student has in-depth knowledge about CDMA techniques and their applications in wireless communications. This course is tought every second year; not taught during Spring 2014.
