WIRELESS COMMUNICATION DEVICE AND METHOD OF RESPONSE SIGNAL EXPANSION Russian patent published in 2013 - IPC H04B1/707 

FIELD: radio engineering, communication.

SUBSTANCE: in a device a control part controls both a sequence ZC, which is used in primary expansion on an expansion part and a Walsh sequence, which is used in secondary expansion in an expansion part, to provide the possibility for a very small cyclic interval of ZC sequence shift to absorb noise components that remain in the response signal; the expansion part uses the ZC sequence set up with the help of the control part for primary expansion of the response signal; and the expansion part uses the Walsh sequence set up with the help of the control part for secondary expansion of the response signal, to which a CP prefix was added.

EFFECT: increased accuracy of signals division with code compaction of a response signal in multiplexing.
