Patent number: 9118401Abstract: A filter for a radio receiving device doubles a sample size of a digital baseband signal to form an enhanced data set and after widowing performs a Fast Fourier Transform (FFT) to facilitate calculation of instantaneous magnitude values and average magnitude values for each of a plurality of frequency bins. A noise floor is calculated based on the average magnitude values of a plurality of the frequency bins, and the noise floor is then used to identify frequency bins which contain an interfering signal. If it is determined that a frequency bin contains spectral energy associated with an interfering signal, then the instantaneous magnitude value of the frequency bin is selectively reduced, after which an inverse FFT operation and inverse window operation is performed.Type: GrantFiled: October 28, 2014Date of Patent: August 25, 2015Assignee: Harris CorporationInventors: John W. Nieto, Carl Petruzelli, Brian C. Padalino

Patent number: 8121236Abstract: A communications system receives a modulated communication signal that carries encoded communications data. A signal input receives the communication signal. An adaptive filter circuit is connected to the signal input and comprises N number of parallel adaptive filters. Each adaptive filter has non-adaptive and adaptive taps with weighted coefficients that are different in number from the respective other parallel adaptive filters within the adaptive filter circuit. A selection output circuit is connected to each adaptive filter and selects for output the adaptive filter having the most suppression or least output power or other criterion which can indicate a best choice to use of the N parallel adaptive filters. A demodulator demodulates the signal and a decoder receives the filtered output signal from the demodulator and decodes the signal to obtain the communications data.Type: GrantFiled: October 12, 2007Date of Patent: February 21, 2012Assignee: Harris CorporationInventors: William N.

Patent number: 8107572Abstract: A communications system receives a modulated signal that carries encoded communications data. An adaptive filter circuit has a plurality of adaptive filters each having a plurality of non-adaptive and adaptive filter taps with weighted coefficients. At a selected adaptive filter, an interference reduction circuit is responsive to one of at least a received state of a demodulator, the type of modulation used by communication system and the input and output power of adaptive filter for updating the adaptive gain of the adaptive filter, selecting the number and order of adaptive filter taps, separating the spacing of multipath introduced by adaptive filter, controlling input and output normalizing circuits to adaptive filter(s) and selecting if signal passed to demodulator is original received signal or signal output by adaptive filter. A demodulator and decoder receive the filtered output signal and demodulate and decode the signal to obtain the communications data.Type: GrantFiled: October 12, 2007Date of Patent: January 31, 2012Assignee: Harris CorporationInventors: William N.

Patent number: 8081722Abstract: A communications device includes a signal input for receiving both wideband and in-band, narrowband communication signals having wideband communications data that is transmitted over a wideband communications channel and narrowband communications data that is transmitted within an in-band, narrowband channels over the same wideband communications channel. A circuit splits the communications signals into a wideband signal channel and narrowband signal channels. A narrowband filter within the wideband signal channel filters the wideband communications signal and removes any narrowband communications signals. A demodulator within the wideband signal channel demodulates the filtered wideband communications signal to obtain any wideband communications data. An in-band, narrowband demodulators are positioned within the narrowband signal channels and demodulate the narrowband communications signals to obtain any narrowband communications data.Type: GrantFiled: April 4, 2008Date of Patent: December 20, 2011Assignee: Harris CorporationInventors: William N.
