Abstract

A low-power architecture for phase-splitting passband equalizer (PSPE) is proposed in this paper. Carrierless AM/PM (CAP) transmission scheme, which is a standard for numerous broadband communication systems including ATM-LAN networks, employs PSPE at the receiving end to combat channel distortion and crosstalk. The conventional PSPE requires two independent adaptive filters that form the in-phase and the quadrature-phase equalizers. The Hilbert relationship between the in-phase and quadrature-phase equalizers in the PSPE is exploited to develop the proposed architecture. It is shown that, by employing the proposed receiver architecture in a 51.84 Mb/s ATM-LAN environment, (i) a net saving in power is obtained as long as the length of the Hilbert filter is less than 130, (ii) a saving of up to 18% can be achieved with a degradation of less that 0.5 dB.
