TRANSMISSION METHOD, AND DEVICE BASING ON OFDM

摘要

A transmission method based on OFDM, including: the transmission data in the frame is divided into at least two domains with variable time length; obtaining the channel information and the traffic, setting different subcarrier bandwidth for each domain according to said channel information, distributing said subcarrier in accordance with said channel information and said traffic, obtaining the time length of every domain according to distributing result, distributing data to domains corresponding to the time length and transmitting them. A transmission method, a transmission device based on OFDM and a method, a transmitter for implementing a frame structure.
