  • Minimizing inter-symbol interference in OFDM signals
    Patent number: 10142154
    Abstract: Methods and OFDM receivers for decoding an OFDM signal include estimating a channel impulse response from a pilot-dense symbol of the OFDM signal for each of a plurality of potential FFT window positions; determining a noise floor of each of the channel impulse responses; selecting the potential window position corresponding to the channel impulse response with the lowest noise floor as an optimum FFT window position; and decoding symbols of the OFDM signal using the optimum FFT window position.
    Type: Grant
    Filed: March 14, 2018
    Date of Patent: November 27, 2018
    Assignee: Imagination Technologies Limited
    Inventors: Mohammed Alloulah, Paul Murrin, Alamo Spaargaren
