Aims and objectives throughout the project
The questions addressed in the TCTE project concern Turbo
CDMA 1 and turbo equalization.
Turbo CDMA :
• design of a multi-user receiver for a CMDA transmitter;
• joint optimisation of multi-user detection and channel decoding;
• applications for UMTS and simulation of the HSDPA 2 system (evolution
of UMTS): implementation of control channels for HSDPA and studies
of the HARQ algorithms for HSDPA.
Turbo equalization :
• implementation of a turbo equalizer with channel estimation on DSP 3
signal processor;
• extension of turbo-equalization to MIMO (multiple-antenna) systems:
studies of MIMO receivers carried out in the frequency domain,
complexity study of iterative MIMO receivers and study of aspects of
synchronization in MIMO.
