Outage based Power Allocation for a Lossy-Forwarding Relaying System

■Abstract

In this paper, an optimal power allocation scheme for a simple lossy-forwarding relaying system is provided. Here, we extend our previous work of optimal power allocation of Slepian-Wolf relay system with constant source-relay error probability, to such that block Rayleigh fading is assumed for all transmission channel and lossy transmission is assumed in source-relay channel. A closed-form expression of the outage probability is derived at high signal-to-noisy ratios regime. It is shown that the outage curves calculated from the closed-form expression are sufficiently close to that obtained by the numerical calculation. Then, the optimum power allocation to the nodes for the system can be formulated as a convex optimization problem. Specifically, we minimize the outage probability while assuming the total transmit power is fixed, and also to minimize the total power under a given outage requirement. It is found that the system performance with the proposed optimum power allocation scheme outperform that with equal power allocation.

■Comment

It is a great honor to win this IEEE Nagoya Section Conference Presentation Award. I would like to sincerely thank all the lab members especially Prof. Tad Matsumoto who has guided and supported this work. In addition, I am grateful to my family for their support which has made this award possible.
