Error Vector Magnitude (EVM)
The error vector magnitude or EVM describes how well the receiver can detect symbols (data) within a constellation
of symbols on the I-Q plane for a particular modulation. It is the difference in RMS power between the point where a
symbol is received and where the symbol should be. This difference is caused by noise. When analyzing EVM, the
lower the number the better.
