The optimal precoding design to maximise capacity of spatially correlated dual‐hop non‐regenerative multiple‐input–multiple‐output relaying systems is proposed. The correlated systems generally have additive coloured Gaussian noise at receive terminals and correlated data symbols at the source. Simulation results show that the capacity of the proposed precoding scheme is significantly higher than those of the existing schemes.
