Abstract:With the rapid development of the communication era,the quality and stability of communication signals have become key factors in future technological competition.An In-depth research on the measurement of key parameters of I/Q signals in zero intermediate frequency architecture was conducted,and a precision measurement method was proposed,based on machine learning that extends the measurement range.The method fully utilizes the advantages of machine learning in signal processing,and can achieve high-precision measurement of I/Q signals through learning and training of a large amount of data.The measurement results of simulation data and actual measurement data were prosented.Through experiments and data analysis,it is found that the superiority of this method in signal measurement accuracy and stability is verified.
