They would drive long poles into the lakebottom within these frames, and then build their houses on these long poles.
他们在这些框内,向湖底打进长木桩,然后在长木桩上修房。

With this method applied the separation of the AM sine pulse from the ideal chaotic signal and from the measured reverberation of the lakebottom are implemented.
