Abstract
In this paper, we present the finite-precision analysis of the pipelined strength-reduced adaptive filter architecture. This architecture provides the dual advantage low power dissipation and high speed operation. Precision requirements for the traditional cross-coupled (CC) and the strength-reduced (SR) architectures are compared. In case of the filter block (F-block) coefficient precision, the SR architecture requires 0.3 bits more that the corresponding block in the CC architecture. Similarly, the weight-update (WUD-block) in the SR architecture is shown to require 0.5 bits fewer than the corresponding block in the CC architecture. This finite-precision architecture is then used as a near-end crosstalk (NEXT) canceller for 155.52 Mb/s ATM-LAN over unshielded twisted pair (UTP) category-3 cable. Simulation results are presented in support of the analysis.
