The capacity of a millimetre-wave (mm-Wave) system can be improved by adopting a hybrid digital-to-analog (D-A) precoding system. Therefore, in this paper, an algorithm is proposed to maximise the capacity of the hybrid D-A mm-Wave system. This algorithm is a geometric approach which is based on the principle of Stiefel Manifold optimisation (SMO). Our proposed algorithm is compared with three known hybrid D-A precoding algorithms in the literature. The analytical and simulation results show that the proposed algorithm achieves higher capacity than the existing hybrid D-A precoding algorithms.
