Publication number: 20200077413Abstract: A radio is disclosed that operates in multipath propagation environments such as obstructed LOS conditions with uncoordinated interference sources in the same operating band. Such a radio may use a combination of interference mitigation procedures across multiple of the frequency, time, spatial and cancellation domains. Such radios may communicate with each other to coordinate radio resource allocations such that accurate interference assessment and channel propagation characteristics assessment may be determined during normal operation.Type: ApplicationFiled: November 7, 2019Publication date: March 5, 2020Applicant: SKYLINE PARTNERS TECHNOLOGY LLCInventors: Kevin J.

Patent number: 8924811Abstract: Disclosed is a decoder having efficient inner and outer decoders for decoding serially concatenated convolutional codes. The decoder comprises a data converter that processes soft demodulator data derived from a demodulator to generate log of probabilities data. An inner decoder is coupled to the data converter and comprises a forward recursion metric in parallel with a backward recursion metric that are coupled to a soft log-likelihood calculation processor and that generate inner decoded soft data. A de-interleaver is coupled to the inner decoder that de-interleaves the inner decoded soft data. An outer decoder is coupled to the de-interleaver that comprises a forward recursion metric in parallel with a backward recursion metric that are coupled to a soft log-likelihood calculation processor that generate outer decoded soft data. An interleaver feeds back the outer decoded soft data to the inner decoder. A decision processor processes the outer-coded soft data to generate decoded data.Type: GrantFiled: January 12, 2010Date of Patent: December 30, 2014Assignee: Lockheed Martin CorporationInventor: Sagnik Ghosh
