| Abstract: |
| The identification and demodulation of the communication signals are important in the communication reconnaissance. Generally many important parameters of communication signals are not known. In this paper, a symbol-rate measurement technology based on delay autocorrelation method is introduced. Simulation and experiment results show that the method has good performance. |
