論述如何在硬體上實現探測聲納系統，包括模擬信號預處理機，數字信號處理機的實現，發射機，接收轉換以及系統的電源設計都給出了具體的硬體實現方案。 -
The approach in this thesis first design the best performance channel code in different channels and different snr, then design the adaptive coder / decoder. the receiver continually estimates the fading and noise of the channel and transmits them to the transmitter by reverse channel. then the transmitter use these information to choose the best channel code adaptive the current channel
本文提出的自適應調制方案首先設計各種通道衰落和信噪比條件下的最優通道編碼，再設計一種能夠完成這些通道編碼解碼的自適應編碼解碼器；接收機不斷估計通道的衰落程度和噪聲功率，並通過反向通道反饋給發射機；發射機據此選用最適合當前通道的通道編碼，實現自適應。
