This paper investigates the challenges of transmitting and receiving information obtained from sensor readings by acoustic excitation of pipe strings interconnected by joints in an ideal environment without external interference. It explores the frequency selectivity of the pipe strings and describe the behavior of passbands as a function of both frequency and propagation distance in addition to the distortion caused by reflections. This paper also looks into the effects of different signaling parameters such as bandwidth, data rate, and carrier frequency and measurement locations on the overall performance of a communication system.
本文研究了在无外部干扰的理想环境中，通过对由接头连接的管柱进行声学激励来传输和接收从传感器读数获得的信息所面临的挑战。它探讨了管柱的频率选择性，并描述了通带特性随频率和传播距离的变化情况，以及反射所引起的失真。本文还研究了不同信号参数（如带宽、数据速率、载波频率）和测量位置对通信系统整体性能的影响。
