摘　　要：针对现有低频通信系统功耗过高、天线尺寸太大、调整不灵活等问题,设计了一种基于FPGA的低频通信系统。研究了基于软件无线电的微弱信号处理方案,设计出高效的低频天线,实现了远距离、大穿透深度的可移动通信。在较强的电磁干扰情况下进行了透地和透水模拟实验,结果表明该系统可以在地面和地下以及地面和水下建立起有效的无线电通信,证明了低频无线通信的发展潜力,可以为实际应用提供参考。According to the existing problems of high power consumption, large antenna and inflexible adjustment of low frequency wireless communication system, a miniature low frequency communication system based on FPGA was designed. Weak signal process- ing scheme based on software radio was researched, and the efficient low frequency antennas was designed. The long distance, large penetration of mobile communication had been achieved. The through-earth-and-water simulation experiment was carried out under the condition of strong electromagnetic interference. The results show that the system can establish effective radio communications be- tween the earth＇s surface and underground or underwater. The results demonstrate the potential development of the low frequency wireless communication and prove the reference value for the practical application.
