The major approaches to the Time-Domain Equalizer (TEQ) design in DMT systems are summarized. After pointing out that the optimal design method of Maximum Shortening Signal-to-Noise Ration (MSSNR) TEQ can’t be real-time implemented by DSP, we present a suboptimal MSSNR TEQ design method, which reduces the computational complexity greatly by using a new method to estimate the optimal delay Δ and a proposed step-by-step algorithm to compute the TEQ taps. The results of simulations show the validity of the suboptimal method.
