Method and digital receiver for receiving orthogonal frequency-division multiplexed signals

摘要: A digital receiver uses a local oscillator to down-convert an orthogonal frequency-division multiplexed signal that has been modulated by differential phase-shift keying, and performs further processing obtain differentially demodulated array of phase values. According first aspect the invention, detects carrier offset, applies corresponding correction values in array, then shifts entire amount offset. As result, need be tuned only frequency range equal subcarrier spacing. second is within spacing multiplied certain integer, shifted multiple this eliminated.
