N2 - This paper considers a hybrid precoder design for millimeter wave systems. The conventional works suffer from performance loss in spectral efficiency, and also suffer from high complexities of optimization algorithms in terms of iteration as well as processing time. This paper proposes a new fast optimization algorithm that improves the calculation algorithm of the gradient and avoids the nested-loop architecture of the state-of-the-art algorithm, MO-AltMin. Exhaustive evaluations demonstrate that the proposed algorithm yields comparable or faster processing speed than the state-of-the-art algorithms while keeping spectral efficiency near-optimal.
