This paper proposes a novel joint hybrid precoder and combiner design for maximizing the average achievable sum-rate of single-user OFDM millimeter wave massive MIMO systems. The analog precoder and combiner design is formulated as a constrained Tucker2 decomposition and solved using the projected alternate least square method. This formulation allows maximizing the sum of the effective baseband gains over every subcarrier while suppressing the interference among the same subcarrier’s data streams. The digital precoder and combiner are obtained from the effective baseband channel’s singular value decomposition on a per-subcarrier basis. Numerical simulation results show that the proposed method outperforms some of the existing designs while having similar computational complexity.
