摘要
为应对在强干扰环境下信息扩频传输的需要,采用扩频芯片Z87200为核心器件,在实验室条件下采用常规元件构建信息扩频解扩传输模块,并进行了大量基带传输实验。实验表明该模块具有易编程、功耗低及抗干扰能力强等优点,可方便地嵌入已有的信息传输系统中。
In need of information transmission under strong interference environment, spread spectrum information transmission modulation and demodulation modules based on Z87200 are designed successfully. Experiments show that the modules have many advantages such as easy-programmability, low power consumption and strong anti-interference capability. The modules can be easily embedded into current information transmission systems and have wider application areas.
