摘要：
A tight lower-bound on the decision-point signal-to-noise ratio (SNR) of the infinite-length minimum mean square error decision feedback equalizer (MMSE-DFE) on additive white Gaussian noise (AWGN) plus NEXT impaired twisted-pair lines is derived in closed form. For the finite-length MMSE-DFE, the performance is completely determined by the maximum diagonal element in a Cholesky factorization of a structured correlation matrix. We illustratze how these results can be used for a quick performance evaluation and optimization of system design parameters.
