Robust frame synchronisation using standard VLSI synchronous input/output devices

摘要

A robust frame synchronisation technique is proposed for serial data links which are to be implemented using standard VLSI synchronous input/output (SIO) hardware devices with a built-in 8-bit frame sync collector. This new technique uses a multiple byte marker and additional software for frame sync, and yields up to 4.6 dB improvement on noisy channels where forward error correction is used and only the SIO hardware is available.
