FINITE-STATE POWER CONTROL FOR FADING CHANNELSy

چکیده
This papers considers the problem of nite-state power control for minimizing the bit-error-rate of uncoded modulation systems over fading channels. Finite-state power control is deened as a power control policy that employs a nite number of distinct power levels, each over a diier-ent interval of the fade depth. We develop an algorithm that determines the optimal nite-state power control and present results for the cases of average and peak power constraints. We illustrate the connection between the average SNR, peak power and required number of states. The ro-bustness of the nite-state power control with respect to channel mismatch is also discussed. The numerical results are obtained for the binary diierential phase-shift keying system over a Rayleigh fading channel.

Optimizing the Transmit Power for Slow Fading Channelsy
We consider the design of power-adaptive systems for minimizing the average bit-error-rate over at fading channels. Channel state information, obtained through estimation at the receiver, is sent to the transmitter over a feedback channel, where it is used to optimally adapt the transmit power. We consider nite-state optimal policies to reeect the limitations of the feedback channel. We develop...
متن کاملPOWER CONTROL SCHEMES FOR FADING ADDITIVE WHITE GAUSSIAN NOISE CHANNELSy
In this paper we propose two novel approaches to the problem of power control for fading, additive white Gaus-sian noise channels, with side information. The objective in the rst scheme is to maximize the capacity of the channel subject to a constraint on the minimum capacity at any given state of the channel. In this scheme we assume perfect knowledge of the channel state. In the second part o...
متن کاملPower Allocation Strategies in Block-Fading Two-Way Relay Networks
This paper aims at investigating the superiority of power allocation strategies, based on calculus of variations in a point-to-point two-way relay-assisted channel incorporating the amplify and forward strategy. Single and multilayer coding strategies for two cases of having and not having the channel state information (CSI) at the transmitters are studied, respectively. Using the notion of cal...
متن کاملQueue length aware power control for delay- constrained communication over fading channels
In this paper, we study efficient power control schemes for delay sensitive communication over fading channels. Our objective is to find a power control law that optimizes the link layer performance, specifically, minimizes the packet drop probability, subject to a long-term average power constraint. We assume the buffer at the transmitter is finite; hence packet drop happens when the buffer is...
متن کاملPower injection of renewable energy sources using modified model predictive control
This paper presents a simple model predictive control (MPC) approach to control the power injection system (PIS) for renewable energy applications. A DC voltage source and a single-phase inverter that is connected to the grid by an LCL filter form the PIS. Grid voltage is considered a disturbance for the system. For eliminating this disturbance, a modified model is proposed. It is usual to ...
