PREAMBLE DETECTION AND SYNCHRONIZATION IN OFDMA WIRELESS COMMUNICATION SYSTEMS

摘要

An embodiment of the invention is a technique for preamble detection and synchronization. A symbol correlation of a sequence of symbols is computed in a correlation window using one of a time-domain correlation and a frequency-domain correlation. The sequence of symbols is received in an orthogonal frequency division multiple access (OFDMA) wireless communication. A symbol is verified from the symbol correlation. The symbol is one of a preamble symbol and a data symbol.
