AN ORTHOGONAL FREQUENCY DIVIDE MULTIPLEXING BASED SIGNAL TRANSMITTING METHOD AND DEVICE THEREOF

摘要

An orthogonal frequency divide multiplexing based signal transmitting method is provided, it includes: mapping the signal to be transmitted into orthogonal codes; performing DFT transform to the signal which is mapped into orthogonal codes; transmitting the DFT transformed signal in the first time domain block composed of continuous sub-carriers and continuous OFDM symbols having the number less than the symbol number of a physical frame, in the form of OFDM. An orthogonal frequency divide multiplexing based receiving method, transmitting device and receiving device are also disclosed in the present invention. By the technical solution provided in the present invention, the orthogonality of the orthogonal codes received at the receiving end can be well improved.
