Abstract
Systems and techniques relating to wireless communications are described. A described technique includes receiving information that is indicative of a wireless communication signal transmitted by a wireless communication device, the wireless communication signal having been generated based on a spreading sequence and a known preamble; determining, based on the received information and the known preamble, an estimation of a first frequency offset using two or more locations for encoding elements associated with the spreading sequence; determining, based on the received information, the known preamble, and the first frequency offset, an estimation of a second frequency offset using two or more locations for symbols associated with the known preamble, the second frequency offset being different from the first frequency offset; and processing the received information based on a combination of the first frequency offset and the second frequency offset.
