Sum-Rate Maximization Based on Power Constraints for Cooperative AF Relay Networks

In this paper, our objective is maximizing total sum-rate subject to power constraints on total relay transmit power or individual relay powers, for amplify-and-forward single-antenna relay-based wireless communication networks. We derive a closed-form solution for the total power constraint optimization problem and show that the individual relay power constraints optimization problem is a quad...

Rate Maximization in Wireless Powered Communication Systems with Non-Ideal Circuit Power Consumption

The key concern in battery-powered communication is the limited power availability and the need for battery replacement. Energy harvesting (EH) wireless communication has promised to tackle these issues successfully by devising optimal policies that take into account the harvested energy causality. This task is particularly challenging if the processing energy cost, caused by the non-ideal circ...

Sum-Rate Maximization with Minimum Power Consumption for MIMO DF Two-Way Relaying: Part I - Relay Optimization

The problem of power allocation is studied for a multiple-input multiple-output (MIMO) decode-and-forward (DF) two-way relaying system consisting of two source nodes and one relay. It is shown that achieving maximum sum-rate in such a system does not necessarily demand the consumption of all available power at the relay. Instead, the maximum sum-rate can be achieved through efficient power allo...

On Sum Rate and Power Consumption of Multi-User Distributed Antenna System with Circular Antenna Layout

We investigate the uplink of a power-controlled multi-user distributed antenna system (DAS) with antennas deployed on a circle. Applying results from random matrix theory, we prove that for such a DAS, the per-user sum rate and the total transmit power both converge as user number and antenna number go to infinity with a constant ratio. The relationship between the asymptotic per-user sum rate ...

Design of an Efficient Circuit for Data Rate Configuration in Power Amplifier Dedicated to Wireless Medical Applications

This paper presents a new circuit to configure power amplifier (PA) for return-to-zero on-off-keying (RZ-OOK) transmitters. The proposed PA works as a multimode structure with configurable data rate and output power. The programmable data rate function is achieved by duty cycle adjustment of input data and producing input RZ-data by a simple circuit, which leads to a linear scale of data rate w...
