The time domain equalizer (TEQ) is used in the discrete multitone (DMT) transceivers in order to reduce the duration of the overall response of the transmission system. The optimum TEQ is the one that results in maximum bit allocation to each block of the DMT. However, the optimum design of the TEQ turns out to be a very difficult task. In an earlier work, we noted that there are some general guidelines that one should follow in the design of the TEQ for achieving a near-optimum performance. There, we proposed an eigen-approach which could result in TEQs with comparable performance to those of a previously reported method, but at a much lower computational cost. We propose a second design method which is even simpler than our first method, but still results in designs comparable to the best available methods
