Patent number: 7593488Abstract: Embodiments of a method and system for determining the presence or absence of a digital communication signal are disclosed. One embodiment of the inventive method comprises the steps of collecting a plurality of signal samples at a selected frequency for a known period of time, determining a metric dependent upon at least one measured characteristic associated with the collected signal samples, and indicating signal status as present when said determined metric is greater than a known value. In another embodiment, the aforementioned method may indicate the signal status as absent when the determined metric is less than the known value. As should be appreciated, embodiments of the inventive method may be used to determine the known value by determining the metric performance for a plurality of samples for a plurality of signal conditions.Type: GrantFiled: April 25, 2003Date of Patent: September 22, 2009Assignee: Harris CorporationInventors: William Nelson Furman, Eric Norman Koski

Patent number: 7577899Abstract: The communication method includes the use of CRC codes for additional error correction in addition to the error detection capability. The method is for error detection and correction in a received message that includes N message bits and M Cyclic Redundancy Check (CRC) bits appended thereto. It is determined whether at least one bit error has occurred in the N message bits and M CRC bits of the received message based upon the M CRC bits, and when at least one bit error is determined, then K bits with a lowest quality metric are selected from the N message bits and M CRC bits. The bit error is corrected based upon possible bit error patterns and the selected K bits. Multiple bit errors may also be corrected.Type: GrantFiled: February 13, 2006Date of Patent: August 18, 2009Assignee: Harris CorporationInventors: John Wesley Nieto, William Nelson Furman

Patent number: 7292640Abstract: Disclosed is an inventive system and method for extracting signal energy from the guard time portion of a communication frame based on the amount of multipath interference experienced by that communication frame. In one embodiment, N blocks of samples are created from the received frame wherein the samples in the guard time portion of the received frame are included in one of more of the N blocks of samples. The estimated symbols, or estimated bits, determined from the received samples are checked for corruption due to multipath interference. For those blocks for which multipath interference is not detected, the estimated symbols, or estimated bits, are coherently added together so as to take advantage of uncorrupted signal energy from the guard time portion of the frame.Type: GrantFiled: October 3, 2003Date of Patent: November 6, 2007Assignee: Harris CorporationInventors: John Wesley Nieto, William Nelson Furman
