Optimal Power Allocation for Multiple Access Channel
International Journal of Wireless & Mobile Networks, 2016 This paper considers the problem of power allocation between the two senders in the multiple access channel. Two power allocation criteria are developed. In particular, in the first criterion, the total available power is allocated between the two users such that the two users have the same achievable rate.

Massive MIMO With Optimal Power and Training Duration Allocation
IEEE Wireless Communications Letters, 2014 We consider the uplink of massive multicell multiple-input multiple-output systems, where the base stations (BSs), equipped with massive arrays, serve simultaneously several terminals in the same frequency band. We assume that the BS estimates the channel from uplink training, and then uses the maximum ratio combining technique to detect the signals ...

Optimal Joint Power and Subcarrier Allocation for MC-NOMA Systems
, 2016 In this paper, we investigate the resource allocation algorithm design for multicarrier non-orthogonal multiple access (MC-NOMA) systems. The proposed algorithm is obtained from the solution of a non-convex optimization problem for the maximization of ...

Advanced Functional Materials, EarlyView.A stacked memristor crossbar architecture is presented that enables direct in‐memory computation of Euclidean distance through intrinsic current subtraction at a shared middle electrode. By physically encoding weights and squared weights in vertically aligned layers, the system realizes energy‐efficient self‐organizing map learning, demonstrating ...

Energy-Efficient Power Allocation for MIMO-SVD Systems
IEEE Access, 2017 In this paper, we address the problem of energy-efficient power allocation in MIMO systems. In fact, the widely adopted water-filling power allocation does not ensure the maximization of the energy efficiency (EE).
