what does the MATLAB function 'helperMIM​OChannelEs​timate' estimates

Does the function helperMIMOChannelEstimate estimates and returns perfect channel estimate or is it using any basic channel estimation algorithm like LS OR MMMSE to calculate it.

Hi ANUSAYA,

The function helperMIMOChannelEstimate uses the least squares (LS) method to estimate the channel impulse response of a multiple-input multiple-output (MIMO) system.
