Method and orthogonal frequency division multiplexing (OFDM) receiver for reducing the influence of harmonic interference on OFDM transmission systems

Image Number 4 for United States Patent #7366088.

A method and OFDM receiver are provided for reducing the influence of harmonic interference on OFDM transmission systems, wherein high interference unity is achieved by the simultaneous use of a window function and a determined item of reliability information, the window function being a Nyquist-shaped window function which generates low side lobes in the subcarrier and interference spectra while simultaneously leaving the orthogonality of the subcarriers unchanged, the determined item of reliability information being derived from a measurement when transmitting a so-called zero symbol, in order to detect the instantaneously active interference signals, with the high interference immunity being achieved when the subcarrier-specific information is taken into account in a so-called Viterbi decoder.
