A variable time lag algorithm for the FIR equalizer
Yu Gong, Colin F. N. Cowan · 2004
In linear equalization, time lag is an important parameter that significantly influences the performance. Only with the op-timum time lag that minimizes the minimum-mean-square-error (MMSE), can we have best use of the available re-sources. Many designs, however, choose the time lag either based on pre-assumption of the channel or simply based on average experience. In this paper, we propose a novel vari-able time lag algorithm with the concept of pseudo fractional time lag. The proposed algorithm can converge to the opti-mum time lag in the mean and is verified by the numerical simulations provided in this paper. 1.
