Error Vector Magnitude Calculation Example

Error Vector Magnitude Calculation Example. 2.9 shows the spectral representation of the walsh series expansion for different m values. The magnitude of a vector formula is used to calculate the length for a given vector (say v) and is denoted as |v|.

IQ Mag and IQ Phase Error (Digital Demodulation) from rfmw.em.keysight.com

So basically, this quantity is the length between the initial point and endpoint of the vector. This matlab function returns a structure, evm, containing error vector magnitude (evm) information for the input array, x, given the reference signal array, r. The spectra are obtained for a number of samples ns =4096.
