Abstract: A high-precision long-distance underwater acoustic ranging method based on low-frequency continuous sound wave peak capture. The ranging method comprises: by means of a characteristic that a magnetostrictive rod itself in a magnetostrictive transducer vibrates under the action of a magnetic field, emitting a sound wave a 0 , and receiving the sound wave a 0  and an echo a 1  reflected by a target object by means of a hydrophone (S130); after performing sound-electricity conversion on the sound wave a 0  and the echo a 1  by using the hydrophone, performing filtering processing to obtain a sampling electric signal s, and then obtaining a distance d of the target object by using peak time t i  according to a time difference relation between the sound wave a 0  and the echo a 1  (S170). According to the ranging method, ranging of the target object is completed by means of a manner of capturing a peak value of an electric signal under a condition that the electric signal subjected to sound conversion is only simply filtered, and the ranging precision is improved.

Abstract: Disclosed in the present application are a communication method and apparatus, used for reducing the signalling overheads when a communication device in a communication system establishes a connection multiple times with another communication device. In the present method, during the process of establishing a connection or after establishing a connection with a second communication device, a first communication device sends a first duration to the second communication device, in order to indicate the duration that the second communication device will store configuration information of the first communication device. When the first communication device establishes a connection with the second communication device again, the second communication device has stored the configuration information of the first communication device according to the first duration, and therefore the first communication device does not need to re-send the configuration information of the first communication device to the second communication device. The present method can reduce the signalling overheads of the first communication device sending configuration information during the process of establishing a connection.
