METHOD, DEVICE AND OFDM SYSTEM FOR RESISTING NOISE IN OFDM SYSTEM

摘要

Disclosed is a method for resisting noise in an OFDM system, comprising: receiving retransmission request information and a noise information detection result of noise causing an error of a data transmission unit; updating a sending parameter according to the retransmission request information and the noise information detection resu sending a data transmission unit according to the updated sending parameter; and detecting the noise information of the noise causing the error of the data transmitting unit, determining the sending parameter according to the noise information, and sending the sending parameter and retransmission information for a peer end to perform data transmission according to the sending parameter. Moreover, further disclosed are a corresponding device and system for resisting noise in an OFDM system.
