Cooperative Decode-and-Forward ARQ Relaying: Performance Analysis and Power Optimization
Abstract--In this paper we develop a new analytical methodology for the evaluation of the outage probability of cooperative decode-and-forward (DF) automatic-repeat-request (ARQ) r...

On the Capacity of Training-Based Transmissions with Input Peak Power Constraints
— 1 In this paper, training-based transmissions over a priori unknown Rayleigh block fading channels are considered. The input signals are assumed to be subject to peak power con...

Performance analysis and adaptive power control for block coded collaborative networks
We derive theoretical bit and frame error rate expressions for decode-and-forward (DF) collaborative networks containing M users, employing a variety of block codes over a Rayleig...

Energy Optimization across Training and Data for Multiuser Minimum Sum-MSE Linear Precoding
This paper considers minimum sum mean-squared error (sum-MSE) linear transceiver designs in multiuser downlink systems with imperfect channel state information. Specifically, we de...

Source fidelity over fading channels: performance of erasure and scalable codes
We consider the transmission of a Gaussian source through a block fading channel. Assuming each block is decoded independently, the received distortion depends on the tradeoff betw...
