3 Terms and definitions
3.1 Intermodulation Distortion. When a composite signal above two frequency components passes nonlinearity
After the network, in addition to the original frequency components and their corresponding harmonic components in the output signal, each frequency is generated.
The sum and difference frequency components of the rate component, which are caused by the mutual modulation and the combined frequency components, are called mutual
Adjust the distortion.
3.2 Vectordiagram. The number is represented by the corresponding point on the coordinate plane (I/Q plane)
The instantaneous value of the modulated vector signal is called a graph (or state diagram), as shown in Figure 1. a plane represents a shape
State, each point represents a vector. Different vectors represent a logical quantity of "0" or "1". Due to the nonlinearity of the RF amplifier
With noise, interference and fading of the transmission channel, etc., the amplitude and phase of the vector change, so the measured vector
The amount is not the same as the reference vector, as shown in Figure 2.
Figure 1 vector coordinate chart Figure 2 error vector
3.3 error vector. equal to the vector difference between the measured vector and the reference vector.
3.4 error vector magnitude (EVM). equal to the magnitude of the error vector. Usually expressed as
The percentage of the peak of the reference vector.
3.5 vector magnitude error (vectormagnitudeerror). equal to the amplitude of the measured vector and the amplitude of the reference vector
The difference between degrees. Usually expressed as a percentage of the peak of the reference vector.
