Abstract
Provided is a method for synchronizing a multiple carrier receiver to receive a transmitted signal. The method includes determining a location of one or more scattered pilot carriers in a received symbol sequence and modulating the scattered pilot carriers in accordance with a single pseudorandom binary sequence. The method also includes performing phase error correction via the modulated scattered pilot carriers.
Claims16
A method for signal processing, the method comprising:
- determining a location of one or more scattered pilot carriers in a received symbol sequence;
- modulating the one or more scattered pilot carriers in accordance with a single pseudorandom binary sequence, wherein a duration of the single pseudorandom binary sequence is at least two symbol times of a same symbol;
- and
- performing phase error correction via the modulated one or more scattered pilot carriers.
A non-transitory computer program product including a computer readable medium storing program code, which when executed by a processor cause the following method to be carried out:
- determining a location of one or more scattered pilot carriers in a received symbol sequence;
- modulating the one or more scattered pilot carriers in accordance with a single pseudorandom binary sequence, wherein a duration of the single pseudorandom binary sequence is at least two symbol times of a same symbol;
- and
- performing phase error correction via the modulated one or more scattered pilot carriers.
A system for signal processing, the system, comprising:
- one or more circuits for use in a receiver configured to operate in an orthogonal frequency division multiplexing (OFDM) system, wherein said one or more circuits are operable to:
- determine a location of one or more scattered pilot carriers in a received symbol sequence;
- modulate the one or more scattered pilot carriers in accordance with a single pseudorandom binary sequence, wherein the single pseudorandom binary sequence is a Gold sequence having a duration of at least two symbol time of a same symbol;
- and
- perform phase error correction via the modulated one or more scattered pilot carriers.
