Abstract:
Automatic modulation recognition is an improving area in signal processing that has been interest of research institutes in recent years. Every signal intelligence system consists of three parts: Front, middle prcessing, Output. which Automatic recognition system is in the middle processing. Vast researches has been done on front and output section. By the way output section demands proper work by modulation recognition section in order to work appropriately. With the right knowledge of the receiving modulation, output section can jam or demodulate the receiving signal by demand. Intrapulse modulation in this research is the meaningful variation of frequency, amplitude or phase of a signal. In this research we will detect LFM, NLFM or CW in a signal by implementing the proposed method on FPGA
