Abstract :
In this paper, a pipelined strength-reduced (PIPSR) adaptive filter architecture is employed as a receive equalizer for 51.84 Mb/s ATM-LAN over unshielded twisted pair category-3 (UTP-3) wiring. This architecture provides the advantage of low-power dissipation and high-speed operation. Simulation results are presented to investigate the effect of level of pipelining on the steady-state signal-to-noise ratio at the slicer (SNRslicer). Simulation results indicate that speed-ups of up to 160 can be achieved with about 0.8 dB loss in SNRslicer
