摘要：

We reformulate the minimum mean squared error (MMSE) solution for time domain equalization (TEQ) in multitone transceivers. We show that the maximum shortening signal-to-noise ratio (MSSNR) and minimum intersymbol interference (min-ISI) TEQs are particular cases of one new formulation. With good channel estimation, the MMSE-TEQ achieves near-optimal rate performance. Our algorithm is less sensitive to channel estimation errors than other methods.
