Investigation of the method of equivalent signals for the reproduction of signals with a normalized error vector magnitude
Abstract
It is shown that the error vector module is one of the main parameters that characterizes the quality of modulation in digital radio communication systems and allows quantitative description of errors in the formation and demodulation of digital signals. The possibility of using a new method to assess the accuracy of determining the magnitude of the error vector is considered. The new method is based on the use of a combination of two sinusoidal signals or signals with amplitude and phase modulation. The advantages and limitations of using this method are investigated.
