A novel analytical approach to optimal base station (BS) location problem is proposed. It is based on the widely used system and propagation path models but, unlike known studies, makes use a convex optimization formulation to minimize the total tran

It is shown that the condition of Theorem 1 in (X. Wu, N. C. Beaulieu, D. Liu, “On favorable propagation in massive MIMO systems and different antenna configurations,” IEEE Access, vol. 5, pp. 5578-5593, May 2017) never holds in practice and that

Gaussian MIMO channel under the joint transmit (Tx) and interference power constraints (TPC and IPC) is studied. A closed-form solution for the optimal Tx covariance matrix in the general case is obtained using the KKT-based approach, up to dual vari

Multi-user Gaussian MIMO wiretap channel is considered under interference power constraints (IPC), in addition to the total transmit power constraint (TPC). Algorithms for \textit{global} maximization of its secrecy rate are proposed. Their convergen

The operational capacity of Gaussian MIMO channels with memory was obtained by Brandenburg and Wyner in [9] under certain mild assumptions on the channel impulse response and its noise covariance matrix, which essentuially require channel memory to b

Favorable propagation (FP) for massive multiple-input multiple-output (MIMO) systems with uniform and non-uniform linear arrays is considered. A gap in the existing FP studies of uniform linear arrays is identified, which is related to the existence
