GRU-based modulation signal recognition method

Abstract

This invention discloses a modulation signal identification method based on a GRU, with the following specific steps: Step 1, the transmitting end generates several modulation signals of different modulation types, processes them through an AMR Input Switcher module, and outputs a modulation signal with an inserted category index, which is then radiated to the air interface channel; Step 2, the interfering end generates an interference signal and radiates it to the target air interface channel to obtain a damaged I / Q signal; Step 3, the receiving end receives the damaged I / Q signal and preprocesses the received signal to identify the preprocessed signal. This invention's method exhibits high identification accuracy under complex environmental conditions such as high-intensity noise interference and channel impairment.
