  • Combined OFDMA preamble index identification, integer frequency offset estimation, and preamble CINR measurement
    Patent number: 7844007
    Abstract: A wireless signal processor for use in identifying a maximum Carrier to Noise Interference Ratio (CINR) associated with a plurality of received OFDMA subcarriers has a candidate generator for forming a plurality of candidate values from a particular set of received subcarriers by forming candidate values based on the received subcarriers in combination with possible integer preamble offsets and possible preamble values. A candidate evaluator selects which of the possible preamble values and integer frequency offset values have the maximum CINR, and provides the maximum CINR with IFO and preamble index as outputs.
