3 terminology and units of measurement

3.1 error vector magnitude errorvectormagnitude, EVM On the vector coordinates (Figure 1), with the decline due to the interference of non-linear RF amplifier noise, transmission channel Down, etc., so that the amplitude and phase of a vector to produce changes in the measured magnitude of the vector difference vector and the reference vector. That A scalar quantity, is usually expressed as a percentage of the peak value of the reference vector. Figure 1 error vector 3.2 phase error phaseerror In the digitally modulated carrier signal, the carrier phase to form a string of symbols of the track phase, the phase of each symbol Difference difference between the regression line. In degrees (°). 3.3 waveform quality waveformquality Applied to the CDMA system metrics, it is related to the ratio of power to total power; power is usually associated It is calculated from the measured cross-correlation signal with a known coding as a reference baseband signals obtained. ......
