Summary

CODA aims at studying coding and modulation schemes that can satisfy the stringent performance requirements of future wireless communications systems, i.e. spectrally efficient transceiver capable of operating in time-varying low SNR channels. This goal is addressed threefold: (i) exploiting spatial diversity in multiple antenna (MIMO) transmission systems, (ii) CSI(Channel State Information) - aware transmission using adaptive coding and modulation matched to the channel spatio-temporal response, (iii) soft iterative detection algorithms (turbo-synchronization and turbo-equalisation techniques).
