干涉通道以有限區塊長度之速率合最大化

Abstract

有鑑於超可靠低延遲通訊是第五代行動通訊的核心目標，因此本篇論文研究以 有限區塊長度將干涉通道之速率合最大化。本文使用混合單調性最佳化法來解決 此非凸函數最佳化問題。 本篇論文提出一個尋找複雜函數的混合單調性表示式之方法，此方法透過尋找 並組合較簡易的混合單調性函數來達成目的。此外，也對於混合單調性最佳化法 進行討論，並分析所得之目標問題的最佳化結果。最後，本文提出一個可行的改 善混合單調性最佳化法之想法作為未來方向。

In view of the goal of ultra-reliable low-latency communication (URLLC) in the 5G communication system, we investigate the weighted sum rates maximization in the K-user interference channel in the finite blocklength (FBL) regime. Mixed monotonic programming (MMP) is applied to solve these non-convex optimization problems. We propose a method to find the MMP representations of complex functions by composing multiple mixed monotonic functions, which are easier to find. Some discussions on MMP and weighted sum rates maximization results are also provided. We state a possible modification of MMP as future work.
