Title:
A SENDING AND RECEIVING METHOD, DEVICE BASED ON OFDM
Document Type and Number:
WIPO Patent Application WO/2008/011834
Kind Code:
A1
Abstract:
A signal-sending method based on OFDM is disclosed and it includes: Divide signal
into two parts at least. Map each part of the signal into an orthogonal code. Make
pre-disposal to the orthogonal code and then send it out. Additionally, a signal-receiving
method based on OFDM is also disclosed and it includes: Make pre-disposal to the
received signal and recover channel signals including orthogonal code. Divide
these channel signals into several parts according to mapping rule which is used
as the signal is sent. Make corresponding disposal and error correction code
decoding to these parts in combination. At the same time, a sending and receiving
device based on OFDM is disclosed also. The sending and receiving system based
on OFDM according to this invention wins stronger anti-jamming ability by improving
the orthogonality among received spreading signal.
