Patent number: 9178550Abstract: Methods and systems for mitigating interference or estimating a covariance matrix in a communication system are disclosed. A method of demodulating a received signal in a communication system can include receiving a first plurality of waveforms, estimating a covariance matrix based on the first plurality of waveforms, determining a spatial filter based on the estimated covariance matrix, receiving a second plurality of waveforms, generating at least one filtered waveform by applying the spatial filter to the second plurality of waveforms, and demodulating the at least one filtered waveform.Type: GrantFiled: May 22, 2014Date of Patent: November 3, 2015Assignee: Silvus Technologies, Inc.Inventors: Anish Narendra Shah, Weijun Zhu, Babak Daneshrad

Patent number: 8948312Abstract: Certain disclosed embodiments pertain to suppressing interference in a wireless communication system. For example, a method of suppressing interference can include receiving one or more first signals including components from a plurality of sub-channels. Each of the first signals can be converted into a respective plurality of first sub-band frequency components. A respective spatial filter can be determined for each frequency sub-band using one or more corresponding first sub-band components for each respective spatial filter. One or more second signals including components from the plurality of sub-channels can be received. Each of the second signals can be converted into a respective plurality of second sub-band frequency components. A corresponding plurality of filtered sub-band components can be generated by applying the respective spatial filters to the corresponding second sub-band components for each of the second signals.Type: GrantFiled: July 12, 2013Date of Patent: February 3, 2015Assignee: Silvus Technologies, Inc.Inventors: Babak Daneshrad, Jean-Francois Frigon, Anish Narendra Shah, Weijun Zhu
