In this paper, we present results from a circuit simulation of a proposed electro-acoustic communications channel. The communications channel was modeled in PSpice using Redwood's version of Mason's equivalent circuit. The simulations used binary phase shift keyed communications signals with a carrier frequency of 1.12 MHz. Results obtained from the model are comparable with the results obtained experimentally. The frequency response of the model matched the measured frequency response, predicting lower frequency resonances obtained in the experimental data. The transient response of the model compares almost identically with the transient response observed experimentally. This is a significant characteristic as the acoustic communications are transient limited, which suggests that the model can be used with good confidence in the optimization of the transducers and algorithms used for acoustic communications.
在本文中，我们展示了对所提出的电声通信通道的电路模拟的结果。该通信通道是在 PSpice 中使用 Redwood 的 Mason 等效电路版本建模的。仿真使用二进制相移键控通信信号，载波频率为 1.12MHz。模型得到的结果与实验结果相吻合。模型的频率响应与实测频率响应相匹配，预测了实验数据中较低频率的共振。模型的瞬态响应与实验观测到的瞬态响应几乎完全一致。这是一个重要的特征，因为声通信是瞬态受限的，这表明该模型可以在优化用于声通信的换能器和算法时被很好地信任。
