摘要
本文阐述了扩频技术的基本原理,提出了一种基于FPGA的直接扩频序列发射系统的实现方案,采用VHDL语言、Altera公司的集成开发环境QuartusII和Stratix系列芯片,完成了对直接序列扩频发射系统的软件仿真和硬件电路设计。该系统采用了直接数字频率合成技术(DDS)和并发处理技术,提高了系统的性能和处理速度,较大程度地减少了硬件延时。
This paper explained fundamental of spread spectrum technology, presented the scheme of achieving direct sequence spread spectrum transmit system based on FPGA, which used VHDL,the integrated developing environment Quartus II and Stratix series chip produced by Altera to accomplish the software simulation and hardware design. The system uses direct digital synthesize （DDS） and parallel processing technique, improves the performance and speed of the processing, and reduces the hardware delay mostly.
