description: The Inverse Discrete Fourier Transform (IDFT) is a mathematical operation used to convert frequency-domain signals into time-domain signals. In 3GPP TS 36.521, IDFT is applied to equalized coefficients to produce demodulated symbols, which are then used to calculate the Error Vector Magnitude (EVM).
explanation: IDFT is classified as a Signal Processing Technique because it is a mathematical algorithm specifically designed for transforming signals between frequency and time domains, a fundamental operation in signal processing.
