Signal Detection for Distributed Space-Time Block Coding: 4 Relay Nodes under Quasi-Synchronisation
Fu‐Chun Zheng, Alister Graham Burr, Sverrir Ólafsson · IEEE Transactions on Communications · 2009
Most research on distributed space-time block coding (D-STBC) has so far focused on the case of 2 relay nodes and assumed that the relay nodes are perfectly synchronised at the symbol level. This paper applies STBC to 4-relay node systems under quasi-synchronisation and derives a new detector based on parallel interference cancellation, which proves to be very effective in suppressing the impact of imperfect synchronisation.
