Executive Summary

The authors derive an adaptive power control method for a collaborative network utilizing partner selection that aims to minimize the Frame Error Rate (FER). They model a Decode-and-Forward (DF) collaborative network under block fading conditions, which contains M independent users utilizing codes, whose performance can be expressed by a Signal to Noise Ratio (SNR) threshold, such as turbo codes. They show that partner selection can reduce system complexity and power allocation can improve the FER performance. They use both a search method as well as a convex deterministic method to demonstrate their power allocation scheme. This paper extends other work in which adaptive power allocation is only applied to limited scenarios.
