Abstract

With the rapid development of communication technology, due to the advantages of high flexibility, good compatibility, wide openness and other advantages of software radio, and it is easy to upgrade and expand the system in the later stage, software radio technology has been applied in many radio engineering occasions, showing broad application prospects. This paper applies the GNU Radio experimental platform, and selects eight modulation methods of AM, DSB, SSB, 2ASK, MASK, 2FSK, 2PSK, MPSK, etc., through the setting of basic parameters such as frequency, phase, FFT points, window function and the setting of channel parameters such as additive white Gaussian noise, frequency offset, epsilon and signal-to-noise ratio range, to obtain different simulated time domain charts, frequency domain charts, waterfall charts, constellation charts, and compare and analyze different signal modulation techniques, understand and master the modulation principles and modulation methods of signals. At the same time, modeled on a number of open source datasets such as RML2016.10A and RML2018.01A, a small sample electromagnetic dataset is formed in the GNU Radio software platform, providing a reliable data set for technical research in the field of electromagnetic space and providing more general options for researchers who design related systems.
