Recently, a time-domain equalizer (TEQ) design for multicarrier-based systems has been proposed which claims to minimize the delay spread of the overall channel impulse response. We show that this is true only in an approximate sense; depending on the channel considered, the loss in delay spread with respect to the true minimum can be significant. An iterative algorithm to find this minimum is presented, whose computational complexity is similar to that of standard TEQ designs like the MSSNR… CONTINUE READING
