摘要:
A system and method for restoring a clipped signal may be used in an optical receiver that detects a clipped modulated optical signal. The clipped modulated optical signal is detected to produce a clipped electrical signal including a series of clipped negative peaks and corresponding positive peaks. The clipped signal may be corrected by detecting at least one trigger peak preceding one or more clipped negative peaks to be restored and generating a replacement tip signal segment for the clipped negative peak(s) to be restored. The replacement tip signal segment may be combined with the clipped electrical signal such that the replacement tip signal segment coincides with a clipped end of the clipped negative peak to be restored to produce a restored negative peak.
