摘要
采用扩频方法进行警报通信的优越性在于用扩展频谱的方法可以提高系统的抗干扰能力。以EPlC12Q240C8N作为核心处理芯器,完成了人防警报信号处理器的硬件电路设计,并进行了详细说明,最后用VHDL语言描述了相关功能。本设计达到了人防警报对抗干扰性能和信号传输低误码率的要求,对以后人防警报系统的升级有着重要意义。
The superiority of using the spread spectrum to communicate lies in that the method of spreading spectrum can increase the feature of anti-interference. The hardware design of the civil air defense warning signal processor is completed, using EP1C12Q240C8N as their core processor, and a detailed illustration is given, then the related functions is described by the VHDL language. This design reached the requirements of strongly anti-interference feature and lower error code rate in the civil air defence alarm system, has a most significance for the upgrading of the civil air defense alarm system.
