Compensation of errors in the local oscillator of an ofdm - receiver

摘要

A receiver for an orthogonal frequency division multiplexed (OFDM) signal includes means (2, 4) for receiving a Fourier Transform (FT) representation of the signal. An inverse Fourier Transform converter (14) changes this representation to the frequency domain. The magnitude (7) and phase (d) of the frequency domain components are derived. A phase error analyser (20) determines any phase errors which are then corrected in a phase error compensator (22). IMAGE
