摘要

我们研究了在云无线接入网络上的传输，其中多个基站(BS)通过有限容量回程链路连接到中央处理器(CP)。专注于最大化允许的和率，我们开发了一个基于点阵的编码方案，该方案推广了该模型的计算前向和连续Wyner-Ziv编码。该方案建立在Cover和El Gamal部分解码-压缩-转发的基础上，并被证明严格优于上述两种流行方案中的最佳方案。通过一些数值算例对结果进行了说明。

Partial compute-compress-and-forward for limited backhaul uplink multicell processing

We study the transmission over a cloud radio access network, in which multiple base stations (BS) are connected to a central processor (CP) via finite-capacity backhaul links. Focusing on maximizing the allowed sum-rate, we develop a lattice based coding scheme that generalizes both compute-and-forward and successive Wyner-Ziv coding for this model. The scheme builds on Cover and El Gamal partial-decode-compress-and-forward and is shown to strictly outperform the best of the aforementioned two popular schemes. The results are illustrated through some numerical examples.
