Energy-Efficient Power Allocation for NOMA With Imperfect CSI
IEEE Transactions on Vehicular Technology, 2019An optimum user power allocation solution to maximize the energy efficiency (EE) in a non-orthogonal multiple access (NOMA) system with imperfect channel state information at transmitter (CSIT) and user quality of service constraint is proposed.

On a Power Allocation Method for IDMA Systems
IEEE Transactions on Wireless Communications, 2008A method was proposed in this journal (vol. 6, no. 1, pp. 192-201, 2007), which tackles a power allocation problem for interleave-division multiple-access (IDMA) systems over fading channels. In this paper, we show that the method may not provide valid solutions in some situations. We illustrate this with many numerical examples.

Power allocation algorithm in MC-CDMA
2002 IEEE International Conference on Communications. Conference Proceedings. ICC 2002 (Cat. No.02CH37333), 2003We propose an algorithm to allocate power among subcarriers in an MC-CDMA system. The optimal power allocation coefficients turn out to be the maximum eigenvalue eigenvector of the modified projection matrix orthogonal to the interference signal subspace. We also present a simple on-off control algorithm to decrease feedback information.

Optimal Power Allocation for SCMA Downlink Systems Based on Maximum Capacity
IEEE Transactions on Communications, 2019Sparse code multiple access (SCMA) is a novel type of non-orthogonal multiple access technology that combines the concepts of CDMA and OFDMA. The advantages of SCMA include high capacity, low time delay, and high date rate.

Power allocation schemes for cognitive radios
2008 3rd International Conference on Communication Systems Software and Middleware and Workshops (COMSWARE '08), 2008Coexistence of one or more cognitive radios with a primary radio where the cognitive radios transmit in a spectrum allocated to the primary radio has been investigated in this paper. We consider two distinct scenarios: one in which the cognitive radios give higher priority to one of the cognitive radios and a second in which all the cognitive radios ...

A Hashing Power Allocation Game in Cryptocurrencies
2018Various crypto-currencies backed by Blockchain technology are now springing up like mushrooms. Miners in these peer-to-peer networks compete to maintain the validity of the underlying ledgers to earn the bootstrapped crypto-currencies. With limited hashing power, each miner needs to decide how to allocate their resource to different crypto-currencies ...

Optimal Energy Efficient Power Allocation With User Fairness for Uplink MC-NOMA Systems
IEEE Wireless Communications Letters, 2019The optimal energy efficient power allocation is investigated for the uplink multi-carrier non-orthogonal multiple access (MC-NOMA) system. Considering the user fairness, the power allocation is formulated as a maximization problem of the system weighted

Power Allocation in Downlink PDMA Systems
2018 IEEE Global Communications Conference (GLOBECOM), 2018Pattern division multiple access (PDMA) is a multi- carrier non-orthogonal multiple access (NOMA), which can meet the requirements of massive user connections and super-high data rate in the fifth generation (5G) wireless networks. In this paper, we work on the optimization of power allocation to improve the performance of the downlink PDMA system ...
