Title:
TRANSMISSION DEVICE, TRANSMISSION METHOD, RECEPTION DEVICE, AND RECEPTION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/080109
Kind Code:
A1
Abstract:
The present technology relates to a transmission device, a transmission method, a reception device, and a reception method that make it possible to perform more efficient signal multiplexing. The transmission device performs control to multiplex and transmit a plurality of chirp signals by offsetting transmission frequencies between the center frequencies of neighboring transmission channels, said chirp signals having been generated by subjecting transmission data to chirp modulation. The present technology can be applied to wireless communication systems.
