What is channel response?
Ch Frequency Response is the frequency response of the channel calculated for each measurement channel. The channel frequency response is related to the Ch Impulse Response through the DFT transform. Background annotation indicates any tones which are in a disabled state for the current measurement.
What is channel impulse response?
Discrete-time equivalent channel model derived from the continuous-time channel model. The channel impulse response is of length Nf, and the coefficients fm(k) represent the convolution of the transmit filter, the actual communication medium, and the whitening matched filter (WMF) [1].
