MOTIVATIONPropeller related acoustic signatures typically exhibit modulationcharacteristics. These modulation characteristics originate from the cavitationprocess that takes place in the water due to the cyclic movement of the propellerThe cavitation process is basically the collapse of air and vapor bubblesdue to variations in the static pressure. These variations in static pressure are aconsequence of the passage of the propeller blades through the water. Thismovement, cyclic in nature, causes amplitude modulation in the static pressureand as a consequence an amplitude-modulated(AM) signal can be detected in areceiverCyclostationary processing techniques have been used to detect andlentify analog and digital communication signals very successfully. Thesetechniques have the advantage of using a more realistic model for the signalthan the stationary model used in most of the more conventional signalprocessing techniquesB BACKGROUNDThe basic elements of cyclic spectral analysis are the time-variant cyclicperiodogram and the time-variant cyclic correlogram. These two functions form aFourier transform pair. This fact is known as the cyclic Wiener relation or thecyclic Wiener-Khinchin relation [Ref. 1: p. 49.1

  • MQTT推送简单例子服务端java代码实现
    IBM的MQTT给了一个PHP的服务端代码,在网上找了一个JAVA实现服务端代码的例子,调通了。如果想做这个例子需要自己用电脑建一个wifi,手机连上这个wifi,代码中要改几个个地方1 android服务里有几个MQTT_HOST是ip地址改成自己wifi的ip;2 服务端的publish方法是用来发送的,第一个参数是客户端id clientId,要改成自己在手机客户端设定的名字,前面还有个域,比如mqttClient.publish("tokudu/"+clientId, message.getBytes(),0, false); 我的clientId是sly。其他的大家就自己研究
