Title:
A METHOD AND DEVICE FOR RECEIVING AND TRANSMITTING OFDM SIGNAL
Document Type and Number:
WIPO Patent Application WO/2008/017256
Kind Code:
A1
Abstract:
A receiving and transmitting method of orthogonal frequency division multiplexing signal and device for communication field are disclosed. At transmitting end, signal sequence is set based on transmitted signal value, different signal sequence is set for different value, each element of the signal sequence is respectively spread with different spreading code, spreading result is combined, and the combined sequence is transmitted with orthogonal frequency division multiplexing mode. At receiving end, signal is received with orthogonal frequency division multiplexing mode, the received signal is de-spread with different spreading code, each dispreading result is a element of dispreading sequence, and received signal value is gained based on corresponding relationship of the de-spread sequence, received signal value and signal sequence.
