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 ...

User scheduling and optimal power allocation for full-duplex cellular networks [PDF]
International Workshop on Signal Processing Advances in Wireless Communications, 2016 The problem of user scheduling and power allocation in full-duplex (FD) cellular networks is considered, where a FD base station communicates simultaneously with one half-duplex (HD) user on each downlink and uplink channel.

Optimal Decoding Order and Power Allocation for Sum Throughput Maximization in Downlink NOMA Systems
EntropyIn this paper, we consider a downlink non-orthogonal multiple access (NOMA) system over Nakagami-m channels. The single-antenna base station serves two single-antenna NOMA users based on statistical channel state information (CSI).

Optimal power allocation in server farms [PDF]
Proceedings of the eleventh international joint conference on Measurement and modeling of computer systems, 2009 Server farms today consume more than 1.5% of the total electricity in the U.S. at a cost of nearly $4.5 billion. Given the rising cost of energy, many industries are now seeking solutions for how to best make use of their available power. An important question which arises in this context is how to distribute available power among servers in a server ...

Optimal Joint Rate and Power Allocation in CDMA Networks [PDF]
, 2007 In this paper we propose a polynomial time algorithm for the optimal rate and power allocation problem in a two cell CDMA network. We assume continuous rates and limited powers for the base stations.
