Through the processing method basing on wavelets, implementing the removing noise about section gauss noise to colure full tv signal, we resolve the theory and practice problems in the processing of weak signal detection
摘要通過基於小波分析的處理方法,實現對彩色全電視信號一段被高斯白噪聲干擾的降噪,解決微弱信號檢測過程中遇到的理論和實踐問題。The tv goniometer is the ground control equipment of a model of anti - tank missile. it uses two ccd cameras and the signal extraction method of background counteract, which can make the guiding process of anti - tank missile wo n ' t interfered by sunlight, firelight of battle field, light, flame tracer etc. it can greatly improve the anti - interfering ability of the anti - tank missile system
該電視測角儀是某型反坦克導彈武器系統的地面控制設備,它採用兩個ccd攝像機和背景抵消的信號提取方法,可使反坦克導彈的制導過程不受太陽的反光、戰場的火光、燈光、曳光彈等干擾。Nowadays, the tv guidance technique using analog signal in the procession of transmission has been mastered proficiently, the conventional analog signal is gradually replaced by the digital signal, because it has many disadvantages, such as its need for wider bandwidth ( 6mhz ), the fact of being vulnerable to the noise, its hardware system is very complex and very hard to establish a common standard, while it also has some problems in the system using digital signal, the main problem is its huge volume of data
視頻信號可分為:模擬信號、模擬和數字信號並存、數字信號。目前,傳輸過程中使用模擬信號的電視制導技術已經比較成熟,但其固有的缺點是:傳輸模擬視頻信號所需帶寬較寬( 6mhz ) ,傳輸過程易受干擾,且硬體系統復雜,不易標準化,使得其逐漸被數字信號所取代。Qpsk modulation for digital television using advanced digital signal processing technology, full compliance with dvb - s standard, the receiving end can be directly used for receiving digital satellite receiver. it must not only be able to achieve a higher utilization of the spectrum, with a strong anti - jamming and high performance. fm microwave equipment and simulation and will be good compatibility
Qpsk數字電視調制器採用了先進的數字信號處理技術,完全符合dvb - s標準,接收端可直接用數字衛星接收機進行接收。它不但能取得較高的頻譜利用率,具有很強的抗干擾性和較高的性能價格比,而且和模擬fm微波設備也能很好的兼容。This kind of product applies to elevators 、 hospitals 、 an intersection 、 factories etc., avoiding any interference to the process of monitoring the image from any kind of furious electromagnetic signal and electric waves signal
本產品主要適用於電梯、醫院、路口、廠區等各種環境,防止監視視頻傳輸過程中受到各種強烈電磁信號及電波信號(如電機、馬達等大功率的瞬間啟動電流干擾等)對視頻信號的干擾。For recent years, adsl has world widely employed and widely used in many aspects such as vod, remote medical treatment and e - shopping etc. but we noticed that the traditional telephone networks are designed for the transmission of low frequency signals, and the adsl ' s frequency rang is from 0 to 1. 104mhz, so we must confront the signal attenuation, the loop line noise impairments, the crosstalk interferences, the bridge tap reflections and the rf disturbances problems and many other problems when transmitting the adsl signals one the telephone networks
近幾年來, adsl在世界范圍內得到充分的使用,廣泛應用於視頻點播、遠程醫療、網上購物等各個方面。但是由於電話線網路是專門為傳輸低頻信號而設計,而adsl的頻譜范圍在0 1 . 104mhz內,因此在傳輸adsl信號時,面臨著信號衰減、線路噪聲、串音干擾、橋接抽頭反射和射頻干擾等等多方面的問題,這就要求在adsl開通之前對線路進行一系列的測試。For instance, civilian authorities may wish to monitor their transmissions in order to implement signal confirmation, interference identification and spectrum management
例如,政府有關職能部門要監視民用通信信號,以實現干擾識別和電磁頻譜管理。分享友人
