| Abstract: | The classification of signal modulation i.s a key in communication systems. Some important technologies are studied in digital receiver based on Software-Defined-Radio. Signal type identification is improved by mending the question that the recognition rate is low in the low Signal Noise Ratio. Time synchronization that is key technology of digital demodulation is realized by software. These arithmetic are validated by computer simulation. |
