Title: Passive phase conjugation underwater acoustic communication method and system thereof
Inventor: SHIMURA TAKUYA
IPC: H04B13/02
Filed: 2005-05-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide a passive phase conjugation underwater acoustic communication method and system thereof with which passive phase conjugation underwater acoustic communication can be carried out with high accuracy without the need for increasing the number of receivers configuring a receiver array.  <P>SOLUTION: In the underwater acoustic communication method, an AUV transmits a transmission signal configured with consecutive sets each comprising a probe signal P and a data sequence D as shown in Fig. 2(A), and the receiver array receives the transmission signal. A time-waveform shown in Fig. 2(B-1) indicates the received signal of consecutive sets each comprising a probe signal P' and a data sequence D' received by one of the receivers configuring the receiver array. A correlation waveform between the probe signal and the data sequence received by this receiver is obtained, A time-waveform shown in Fig. 2(C-1) indicates this correlation waveform. Then an adder obtains the sum of correlation waveforms output from all the receivers configuring the receiver array. This results in a data sequence given by the time-waveform shown in Fig. 2(D). The receiver array applies adaptive filter processing to the data sequence to recover a data sequence with a time-waveform from which a noisy signal component is eliminated shown in Fig. 2(E).  <P>COPYRIGHT: (C)2007,JPO&INPIT
