Realization and Optimization of Hilbert Based on Modulation Recognition of Communication Signals

Instant character parameter of signals derives from the analytic signals after hilbert transformation, the capture of complete information of signals request exact and high-speed hilbert transformation. This paper optimizes hilbert transformation with both algorithm and hardware structure as a result of 50% resource saved and validation of emulator is done. It is realized the algorithms can be used in real-time system of signals modulation recognition.
