細胞神經網（CNN）是一種大規模非線性模擬電路。它的兩個重要特點是時間連續特性和局部連接特性，這使CNN 在數字領域能實現實時、高速、并行的信號處理，并特別適于大規模集成電路（VLSI）的實現。本文闡述了CNN 的結構和特點，并介紹了CNN 在通信系統中的應用，主要包括信號處理及其硬件實現、混沌通信和通信中的優化問題等方面。

Abstract：Cellular neural network(CNN)is a kind of large-scale nonlinear analog circuit. It shares two key features: its continuous time feature allows real-time and high-speed parallel signal processing in the digital domain and its local interconnection feature makes it tailor made for VLSI implementation. This paper describes the architecture and features of CNN and introduces its application in the communication system, including signal processing and its
hardware implementation, chaos communication and the optimization problems for communication networks.
