It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.Patent ReferencesTime diversity receiver for processing repeatedly received signal bits in consideration of a maximum-level and/or a favorably received signal bit Method for recognizing digital information transmitted in a mobile radio communication system Satellite communications system and apparatus Method and apparatus for data transmission using chirped frequency-shift-keying modulation Method of, and apparatus for, frequency-hopped frequency-shift-keyed digital data communications Data detector using probabalistic information in received signals Frequency hopping data communication system Frequency hopping data communication system Digital hopped frequency, time diversity system Digital transmission system Patent #: 4621368 InventorsAssigneeApplicationNo. 07/013554 filed on 02/11/1987US Classes:375/347, Diversity (frequency or time)340/310.12, Modulation technique340/310.13, Noise reduction (e.g., filtering)375/135TransmitterExaminersPrimary: Griffin, Robert L.Assistant: Chin, Stephen Attorney, Agent or FirmInternational ClassesH04B 3/54 (20060101)H04L 1/02 (20060101) Foreign Application Priority Data1986-02-27 DEAbstractA method for transmitting data via the power system line of a power supply system by carrier frequency modulation, wherein an improvement in the reliability of transmission is achieved by transmitting the same information several times in succession (time diversity) of different carrier frequencies (frequency diversity). Additional coding of the data by a "forward error correction code" results in further improvement. | |
