Abstract
A method and structure that reduces the computational requirements of both echo cancellation and time domain equalization in symmetrical transceivers. The structure exploits pole-zero modeling of both the echo and transmission path response in order to realize an improved level of system performance with shorter filters than would be required with direct FIR modeling.
