Abstract
This paper presents an energy-efficient implementation of frame-level synchronization for discrete multitone (DMT) wireline transceivers (TRX). Simplifying arithmetic precision for computing cross-correlation (Xcorr) can increase the required length of the synchronization sequence (SS) to achieve the target false positive (FP) error probability. From the software simulation, we found that Lss = 128 with 1-bit quantization is sufficient to reach a 1×10-30 error probability while optimizing energy efficiency and area, when communicating over a channel with a 16 dB loss at Nyquist.
