DETECTION OF PREAMBLES AND SYNCHRONISATION IN OFDMA-SYSTEMS OF WIRELESS COMMUNICATION Russian patent published in 2011 - IPC H04K1/10

Abstract RU 2427959 C2

FIELD: information technologies.

SUBSTANCE: symbol correlation of symbols sequence is calculated in a correlation window with the help of one of time area correlations and frequency area correlation. Sequence of symbols is received according to the method of wireless communication with multiple access with orthogonal frequency division of channels (OFDMA). The symbol is verified from a symbol correlation. The symbol is one of a preamble symbol and a data signal.

EFFECT: improved accuracy of preamble detection and synchronisation.
