Three-dimensional quick capturing method for hopping spreading code phase and carrier wave Doppler

The invention discloses a three-dimensional quick capturing method for a hopping spreading code phase and a carrier wave Doppler. The method includes: firstly, obtaining a local frequency-hopping carrier wave through a frequency synthesizer by using a local frequency-hopping pattern, and performing de-hopping and low-pass filtering to received signals; then, performing figure automatic gain control to data acquired after low-pass filtering, and extracting the data according to a corresponding ratio, and reducing operation amount of subsequent processing; and finally, producing a local direct sequence codon to de-spread the extracted data, and then performing a first accumulation, and performing a second accumulation after accumulated data frequency-hopping phase rotates, performing FFT (fast fourier transform) to the accumulated data, and finding a maximum peak by comparison. A local hopping spreading code phase and a frequency value corresponding to the maximum peak are a hopping spreading code phase and a carrier wave Doppler of the received signals. By the aid of the method, quick and simultaneous capturing of the hopping and spreading code phase and the carrier wave Doppler of a DS / FH (direct sequence / frequency hopping) mixing spread spectrum system under a strong interference condition is realized, and the method is low in realization complexity degree and has a fine anti-interference performance.

Music similarity processing method

The present invention provides a music similarity processing method which comprises the following steps: after inputting first characteristic information of multimedia information of first music or the multimedia information of first music, extracting first characteristic information from the multimedia information of first piece of music; decomposing the first characteristic information to a plurality of information segments which start from a random starting point and have a certain length; after inputting the second characteristic information of multimedia information of second piece of music or inputting the multimedia information of second piece of music, extracting the second characteristic information from the multimedia information of second piece of music; calculating the information similarity data of a random segment of a plurality of information segments and a random segment in the second characteristic information; selecting a maximum value of similarity from the similarity data; and determining whether the maximum value of similarity exceeds the preset threshold. If the preset threshold is exceeded, high similarity between the first piece of music and the second piece of music is determined, and otherwise low similarity between the first piece of music and the second piece of music is determined.

FM and PM signal carrier capturing method applicable to random modulation degree

The invention provides an FM and PM signal carrier capturing method applicable to a random modulation degree. The method comprises following steps of firstly, carrying out down-sampling filtering to input digital baseband signals, thus obtaining down-sampled digital baseband signals; then respectively mixing the digital baseband signals with multiple groups of set local carriers, thus realizing frequency spectrum shift of the baseband signals; carrying out FFT conversion to each frequency spectrum shift branch signal; calculating the power of each spectrum line; searching spectrum line peak values region by region; storing searching results; after a plurality of times of searching is finished, carrying out frequency point verification; eliminating noise interferences, thus obtaining true signal spectrum lines; finally carrying out symmetry judgment to the obtained true signal spectrum lines, thus determining a capturing result. According to the method, the frequency resolution is improved through the frequency spectrum shift; the peak values are searched region by region in the whole capturing range according to the frequencies; the true signals are counted through many times of capturing; the weak signals can be searched in a low signal to noise ratio environment; and the method is applicable to FM and PM signal carrier capturing of random modulation degree.
