摘要:

直接序列扩频通信系统以强抗噪声、低截获性和多址通信等特点,在军事及民用移动通信网络中得到广泛应用。文中对直序扩频的FPGA实现技术进行了研究。以Quartus II为开发工具,建立了一个初步的直接序列扩频通信系统。设计了发射模块和接收模块,发射模块包括PN码产生器、扩频调制器、接收模块包括匹配滤波器和解扩器;给出了上述模块的实现电路及仿真结果。

关键词: 直序扩频, FPGA, PN码, 匹配滤波器

Abstract:

The direct sequence spread spectrum communication (DSSS) is widely developed in military and personal mobile communication for its advantages of high noise resistance,low interception probability,multiple-access communication ability.How to implement a direct sequence spread spectrum communication system used FPGA is researched.A DSSS included transmit and receive module is established based on QUARTUS II.The transmit module is combined with PN generator,spread spectrum modulator,the receive module is combined with match filter and de-spread demodulator.The circuit design and its results are given.

Key words: direct sequence spread spectrum;FPGA;PN code;match filter
