| Abstract: | By means of analyzing the frequency spectrum characteristics of domestic frequency--shift track signal we propese a technical improvement solution to it based on the orthogonal theory and demodulation technology in modern digital signal processing to guaranteed the solution accomplishes the optimized reception at the receiver, thereby enhance system reliability and quality. At same time we simulat-ed this solution with MATLAB, and implemented it on the vc33 experimental platform of floating-point Digital Signal Processing (DSP). |
