H04K3/228 - CPC Classification

Classification description:

Jamming of communication; Counter-measures; Countermeasures against jamming including jamming detection and monitoring with countermeasures at transmission and/or reception of the jammed signal, e.g. stopping operation of transmitter or receiver, nulling or enhancing transmitted power in direction of or at frequency of jammer Elimination in the received signal of jamming or of data corrupted by jamming
