Title:
MICRO-FREQUENCY HOPPING METHOD AND MICRO-FREQUENCY HOPPING MULTIPLE ACCESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/105588
Kind Code:
A1
Abstract:
Disclosed are a micro-frequency hopping method and a micro-frequency hopping multiple access communication system. The micro-frequency hopping method comprises: performing frequency hopping on a time domain baseband signal by taking a subcarrier frequency point as the basic unit in a frequency domain direction and taking a sampling point as the basic unit in a time domain direction. The micro-frequency hopping multiple access system comprises: a baseband signal of a single user for micro-frequency hopping being a baseband signal comprising only one subcarrier in one symbol; and performing micro-frequency hopping on the baseband signal, comprising only one subcarrier in one symbol, of each user by using preset unrelated micro-frequency hopping patterns among a plurality of users.
