基于线性反馈移位寄存器和CSA算法的CA系统加扰模块设计

A Design of Scrambling Module in CA System Based on LFSR and CSA Algorithm

简要介绍CA系统及其加扰模块,具体分析选用线性反馈移位寄存器作伪随机序列发生器、采用CSA算法作为加扰算法的一种CA系统加扰模块的设计方案,前者易于硬件实现、后者易于软件实现使得该方案具有可行性。

In this article firstly describe the structure of the CA system and scrambling module briefly, then analyze a scheme for design of scrambling module in CA system based on LFSR and CSA algorithm. According to the characteristic of the former one is easy to be quickly achieved by hardware and the later one is easy to be quickly achieved by software, made the scheme to be feasible.
