BEAT NOISE SUPPRESSION METHOD AND DEVICE

摘要

Provided are a beat noise suppression method and device, the suppression method comprising: a receiving device in an optical access network receives a null carrier from a transmitting device; the receiving device loads onto the null carrier an OFDM signal after carrierless amplitude modulation (CAP), and transmitting to the transmitting device the null carrier having the OFDM signal loaded. The technical solution provided in the present invention solves the technical problem in the related art that existing beat interference noise suppression solutions do not meet performance requirements of future communication systems, and the present invention integrates null carrier backhaul technology and CAP modulation technology to improve the performance of an optical access network communication system.
