Abstract: Digital and analog modulation communication signal is an important characteristic parameters, and the rapid detection and identification of digital analog communication signal modulation,is extremely important in military and ci vilian aspects. Based on law, this paper proposes an automatic recognition algorithm, which can be used to detect and i- dentify 11 types of signals and implementation process of the analysis and simulation results verifies the effectiveness of the algorithm. When SNR)9dI3, the algorithm average success rate of recognition can be)97 0 o. The communication system can be applied to the actual signal for the rapid detection and identification.
Key words: Digital and analog signals, Automatic recognition, Decision laws
