Transmitter channel tracking for optimal power allocation
2001 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings (Cat. No.01CH37221), 2002The design of accurate equalization schemes, optimizing the transmission strategy, can be achieved if channel status information is available not only at the receiver but also at the transmitter side. Accordingly, we propose a feasible scheme to track the channel response by the transmitter based on channel prediction, becoming a suitable solution in ...

Optimization of the regional allocation of wind power capacity
2019 International Conference on Power Generation Systems and Renewable Energy Technologies (PGSRET), 2019With the growing impact of global warming and depletion of fossil fuels, the necessity of renewable energy resources is becoming more and more obvious. However, investing in intermittent renewable resources, such as wind power, by only considering the regional power potentials jeopardizes system reliability and increases the necessity of spinning ...

Optimization of Power Allocation for Interference Cancellation With Particle Swarm Optimization
IEEE Transactions on Evolutionary Computation, 2009In code division multiple access (CDMA) systems a significant degradation in detection performance due to multiuser interference can be avoided by the utilization of interference cancellation methods. Further enhancement can be obtained by optimizing the power allocation of the users.

Joint Optimization for Optimal Power Allocation in OFDMA Femtocell Networks
IEEE Communications Letters, 2016This letter is concerned with the optimal power allocation in femtocell networks using a new technique based on multiobjective optimization. In this letter, we consider a cochannel framework for the coexistence of orthogonal frequency division multiple access (OFDMA)-based macrocell and femtocell networks.

Optimal Power Allocation for Cooperative Spectrum Sensing
2019 IEEE International Symposium on Dynamic Spectrum Access Networks (DySPAN), 2019In this paper, we propose to optimize the power of Primary User (PU) and secondary relays R k to maximize the Detection Probability (DP). We suggest to maximize the detection probability of cooperative spectrum sensing with relay selection. One relay is chosen to amplify the PU signal to the fusion center D where spectrum sensing using the Energy ...

Power Allocation Optimization in the Presence of Stimulated Raman Scattering
2021 European Conference on Optical Communication (ECOC), 2021We leverage the simplicity of closed-form expressions of the nonlinear interference variance in the presence of stimulated Raman scattering (SRS) for fast pre-emphasis optimization in wideband wavelength division multiplexing (WDM) terrestrial systems with sparse dynamic gain equalizers.

Optimal Power and Bit Allocation for Graph Signal Interpolation
2018 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2018We study centralized interpolation of bandlimited graph signals at a fusion center (FC), when sampled data are transmitted over rate-constrained links. In such a scenario, the performance of the reconstruction task is inevitably affected by several sources of errors such as observation noise and quantization due to source encoding.

Optimal Power Allocation in a Relay-aided Cognitive Network
Proceedings of the 12th EAI International Conference on Performance Evaluation Methodologies and Tools, 2019In this paper, we address a power allocation problem in a relay-aided cognitive network. The network is composed by a primary and secondary user/destination pair and a relay, which helps the communication between the secondary user and its destination.

Asymptotically optimal power allocation with MMSE receivers
International Symposium onInformation Theory, 2004. ISIT 2004. Proceedings., 2004The optimal power allocation scheme is investigated with random spreading sequences and linear MMSE receivers in the regime of large system. The main result is the identification of a power allocation and admission control scheme that maximizes the sum ...
