Master Thesis in Digital Signal Processing
Background: 3GPP has studied how to increase the data rate above EDGE data rates for GSM systems, the study is called "HUGE". In the report from the studies new higher order modulation schemes, 16-QAM and 32-QAM, together with new channel coding schemes are proposed. The modulation schemes are less robust than the currently used GMSK and 8-PSK and require a more complex receiver.
Objective: The outcome of the Master's Thesis should be a recommendation of an equaliser with good performance for "HUGE" that can be implemented with today's technology.
Procedure: Investigate possible receiver structures, especially the equaliser, from performance and implementation point of view. The study will mainly be carried out as literature studies and computer simulations. Example of equaliser candidates are RSSE and DFSE and modification of these. Due to the higher sensitivity for noise and other impairments it might also be necessary to look into details for channel estimation, pre-filter, adaptivity, soft-value extraction etc.
Prerequisite: The student should have a strong background in communication theory and digital signal processing, experience of programming in C and MATLAB. Experience of programming digital signal processors is an advantage.
