  • Methods and devices for interference variance estimation and interference cancellation
    Patent number: 10404506
    Abstract: An interference variance estimation method includes receiving a composite sample comprising a sample of a first OFDM transmission scheme interfered by out-of-band interference of a second OFDM transmission scheme; determining for each of the resource elements of the first transmission scheme a power estimate of the out-of-band interference; and filtering the power estimates over subcarriers corresponding to a same symbol, wherein weights of the filtering are based on a correlation property of the power estimates with respect to the subcarriers. An interference cancellation method includes: receiving the composite sample; determining a first estimate of the out-of-band interference with respect to non-data bearing subcarriers; determining a second estimate of the out-of-band interference with respect to data bearing subcarriers based on the first estimate; and cancelling the out-of-band interference based on the composite signal and the second estimate.
