Title:
WIRELESS COMMUNICATION SYSTEM, WIRELESS COMMUNICATION METHOD, TRANSMISSION ADAPTER DEVICE, AND RECEPTION ADAPTER DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/007630
Kind Code:
A1
Abstract:
This wireless communication system comprises: a transmission adapter device connected to a transmission burst modem device; and a reception adapter device connected to a reception burst modem device. The transmission adapter device generates a corrected burst signal by adding a phase synchronization signal including a random bit to a pre-stage of a preamble signal of a burst signal input from the transmission burst modem device. In addition, the transmission adapter device generates spectrum decomposition signals by decomposing the corrected burst signal into a plurality of sub-spectra. The reception adapter device receives the spectrum decomposition signals, and estimates a phase difference between the plurality of sub-spectra on the basis of the plurality of sub-spectra of the spectrum decomposition signal that corresponds to the phase synchronization signal. The reception adapter device generates a spectrum synthesis signal by synthesizing the plurality of sub-spectra while compensating for the estimated phase difference, and outputs the spectrum synthesis signal to the reception burst modem device.
