SPACE-TIME SCRAMBLING IN SYSTEMS OF CELLULAR COMMUNICATIONS Russian patent published in 2010 - IPC H04L1/06 

Abstract RU 2391781 C2

FIELD: information technologies.

SUBSTANCE: one flow of data symbols is generated, reflected to one or several physical channels, and expanded with the help of channeling codes for physical channels. Space-time scrambling is performed at least in one flow of data symbols for generation of at least two output flows of elementary signals. Space-time scrambling may be achieved by matrix multiplication relative to sequence of matrices. For each time interval, in which space-time scrambling is performed, a matrix may be selected (for instance, on the basis of scrambling code for basic stations), and data sent in time interval is multiplied by selected matrix. Matrices used for space-time scrambling may be determined and selected in a different manner. Output flows of elementary signals are processed and sent via according transmitting antennas.

EFFECT: improved accuracy of measurements in wireless channels.
