H04B 7/0413 MIMO systems
Introduced: January 2017
Full Title
Full titles differ between systems:
Radio transmission systems, i.e. using radiation field > Diversity systems; Multi-antenna systems, i.e. transmission or reception using multiple antennas > using two or more spaced independent antennas > MIMO systems
Radio transmission systems, i.e. using radiation field (H04B10/00, H04B15/00 take precedence) > Diversity systems; Multi-antenna system, i.e. transmission or reception using multiple antennas (RAKE receivers H04B1/7115) > using two or more spaced independent antennas > MIMO systems
IPC and CPC are identically structured here. All 4 subcodes exist in both systems.
1 shared codes have differing titles between IPC and CPC.
IPC defines codes here since 2017.
