coding (QO-STBC) is exploited within a four relay node transmission
scheme to achieve full-rate and increase the available
diversity gain provided by earlier two relay approaches. The
problem of imperfect synchronization between relay nodes
is overcome by applying a parallel interference cancellation
(PIC) detection scheme at the destination node. Bit error rate
simulations confirm the advantages of the proposed methodology
for a range of levels of imperfect synchronization and
that only a small number of iterations is necessary within the
PIC detection
