Impulsive interference noise reducing method for orthogonal frequency division multiplexing signal, involves eliminating part of impulsive noise in equalized signal based on estimated impulsive noise

摘要

The method involves equalizing an orthogonal frequency division multiplexing signal. An impulsive noise is estimated in the equalized signal based on an approximation of the total noise in the equalized signal. A part of the impulsive noise is eliminated in the equalized signal based on the estimated impulsive noise. An independent claim is also included for a device of reducing noise in a received multiple carrier modulation signal.
