Abstract
The present invention is a double-layer multi-carrier ultra-wideband wireless communication method, wherein the frequency band for ultra-wideband communication is divided into a plurality of sub-bands, then one or more sub-bands are used for data transmission, and the Orthogonal Frequency Division Multiplex (OFDM) multi-carrier transmission technology is used in each sub-band. In the transmitting party, the data symbols to be transmitted are allocated on M branches corresponding to the M sub-bands, and the OFDM modulation is implemented on the data symbols on each branch to obtain M branches of parallel data, then digital baseband multi-carrier modulation is implemented on the M branches of parallel data. Thereby, the spectrum of data on each branch is moved onto the digital sub-band corresponding to the radio sub-band one to one, so the digital baseband signal of the radio signal to be transmitted is obtained. Then, the digital signal is converted to an analog signal with a D/A conversion and an up-conversion, and the signal spectrum is moved to the radio frequency band in use, then the analog signal is amplified, filtered and transmitted via an antenna, thus the task of modulatin…
