Competences and Offers for cooperation

 Design of improved MIMO radio interfaces for OFDM modulated systems  Space-time bit-interleaved coded modulation  Performance evaluation  Transmitter design  Efficient receiver implementation Competence # 1 Coded MIMO-OFDM

 Coding for OFDMA systems  Besides OFDM, we are interested to other schemes  Single carrier transmissions with cyclic prefix insertion (CP-SC)  Multicarrier modulators adopting shaping filters (Shaped-OFDM, Filtered Multitone)  Comparisons among these solutions  Performance evaluation  Transmitter and receiver design  Low complexity solutions  Extension to OFDMA environments Offers for Cooperation # 1 Coded MIMO-OFDM

 Linear and non-linear precoding schemes for the MIMO broadcast channel (MIMO-BC)  Achieving performance close to “dirty paper” coding Vector precoding with peak power reduction by modified sphere encoder Study of the optimal (max sum capacity / max min SINR) beamformer for lattice precoding schemes Comparison between Tomlinson-Harashima based precoders and vector-perturbation techniques for MIMO channels Joint activity with EURECOM (G. Caire)  Low-complexity joint detectors for SC-MIMO systems  Frequency-domain algorithms for multi-stream interference cancellation (BLAST) Competence # 2 Single Carrier MIMO

Competence # 3 MIMO MC-CDMA  Design of receivers for MC-CDMA systems  Soft interference cancellation techniques  Pre-equalization techniques for MC-CDMA systems  Multi-user pre-equalization for downlink MISO  Single user pre-equalization for uplink  DSP platform for MC-CDMA  Software defined radio platform with DSP Texas Instruments C6400 Dual ADC and DAC FPGA

 Receivers design for MIMO multi-user MC-CDMA systems  Investigation on V-BLAST receivers for multiple-input multiple- output (MIMO) extended to multi-user MC-CDMA systems  In particular, the work will focus on finding suitable ordering criteria to demodulate symbols and streams of each user  In uplink coded MC-CDMA systems, possible schemes to iteratively combine V-BLAST detection and decoding will be investigated (turbo principle)  Pre-coded MIMO MC-CDMA systems  Investigation on non-linear precoding schemes for downlink Offers for Cooperation # 2-3 MIMO MC-CDMA
