Abstract:
An example system comprises a first antenna and a modem. The first antenna is configured to receive a signal from a transmitting radio frequency unit. The signal includes data and a known sequence. The modem is configured to retrieve the known sequence from the signal, transform the known sequence and the data into a frequency domain, calculate averages of groups of neighboring frequency points in the frequency domain to reduce the effect of nonlinear noise in the signal, the neighboring frequency points corresponding to the preamble in the frequency domain, compare the calculated averages to an expected frequency response in the frequency domain, determine a correction filter to apply to the data based on the comparison, apply the correction filter on the data in the frequency domain to create corrected data, transform the corrected data from the frequency domain to the time domain, and provide the data.

Claim (Index 11):
A method performed by a communication device, the method comprising:\n receiving a signal from a transmitting radio frequency unit, the signal including a preamble containing bits for a known sequence of a predetermined length; transforming the preamble from a time domain into a frequency domain, the transforming the preamble into the frequency domain causing generation of preamble-based frequency points in the frequency domain; grouping neighboring frequency points of the preamble-based frequency points in the frequency domain to generate one or more groups of neighboring preamble-based frequency points, each group of neighboring preamble-based frequency points including a particular number of neighboring preamble-based frequency points, the particular number being based on an amount of error in the signal; generating a representative point in the frequency domain for each group of neighboring preamble-based frequency points; comparing each representative point to an expected frequency response in the frequency domain, the expected frequency response being based on the known sequence of the predetermined length in the frequency domain, the comparison to be used to determine an effect of nonlinear noise in the signal; determining a correction filter based on the comparison to apply to data received by the antenna, the correction filter configured to reduce the effect of the nonlinear noise on the data; transforming the data received by the antenna from the time domain to the frequency domain; applying the correction filter to the data in the frequency domain to create corrected data in the frequency domain; transforming the corrected data from the frequency domain back to the time domain; and providing the corrected data for processing.
