Optimal Power Allocation for Multiple Access Channel

چکیده

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. In addition, the second criterion allocates the total available power such that the sum rate is maximized. In addition, many numerical examples are shown to show the value of power allocation and also to compare between the proposed criteria.

Power and Channel Resource Allocation in Cooperative Multiple Access Schemes Power and Channel Resource Allocation in Cooperative Multiple Access Schemes

In this thesis, we develop efficient algorithms for the jointly optimal power and chan­ nel resource allocation in different wireless cooperative multiple access systems. In addition, in some cases insight into the structure of the optimal allocation enables the development of modified cooperation schemes with better performance, and efficient algorithms are developed for jointly optimal power ...

A Fair Power Allocation for Non-Orthogonal Multiple Access in the Power Domain

This paper presents an investigation on the performance of the Non-Orthogonal Multiple Access (NOMA) in the power domain scheme. A Power Allocation (PA) method is proposed from NOMA throughput expression analysis. This method aims to provide fair opportunities for users to improve their performance. Thus, NOMA users can achieve rates higher than, or equal to, the rates obtained with the convent...

Optimal Power Allocation Scheme for Non-Orthogonal Multiple Access With α-Fairness

This paper investigates the optimal power allocation scheme for sum throughput maximization of non-orthogonal multiple access (NOMA) system with α-fairness. In contrast to the existing fairness NOMA models, α-fairness can only utilize a single scalar to achieve different user fairness levels. Two different channel state information at the transmitter (CSIT) assumptions are considered, namely, s...

Optimal Power Allocation and Performance Analysis of Cooperative Multicast Systems Using Non-Orthogonal Multiple Access

For cooperative multicast systems using nonorthogonal multiple access, we propose optimal power allocation to maximize the achievable rate, and present its performance analysis in terms of average achievable rate and outage probability assuming Rayleigh fading channels. To perform the optimal power allocation, the source requires instantaneous channel information for a subset of the links. In t...

State Estimation Over Wireless Channels Using Multiple Sensors: Asymptotic Behaviour and Optimal Power Allocation

This paper considers state estimation of linear systems using analog amplify and forwarding with multiple sensors, for both multiple access and orthogonal access schemes. Optimal state estimation can be achieved at the fusion center using a time varying Kalman filter. We show that in many situations, the estimation error covariance decays at a rate of 1/M when the number of sensors M is large. ...
