Patents by Inventor Brian Chadwick Joseph

Brian Chadwick Joseph has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8396142
    Abstract: A system, method and computer-readable medium for encoding and decoding digital information over a channel is provided. Type Mapping is employed and is based on the partitioning of vectors over an alphabet into “types” and using enumeration for the encoding and decoding process. Type mapping allows for signal alphabets of arbitrary size and date rate flexible coding. Tradeoffs between optimal rate versus Signal to Noise Ratio are provided and works as a compliment to the Forward Error Control that may be employed in communications products.
    Type: Grant

  • Patent number: 8204460
    Abstract: A method for precise transmit power adjustment in a wide personal area network (WPAN) is provided that includes coarse adjusting a power level of the radio signal by adjusting a gain setting of an amplifier that is used to power the radio signal, and fine adjusting the power level of the radio signal by adjusting a voltage level of an information signal that is provided to the amplifier so that the power level of the radio signal approaches a maximum allowable power level.

  • Patent number: 8081691
    Abstract: A method, system, and computer-readable medium for detecting an interferer in a wireless communication system are provided. The method includes receiving a signal having P tones, each of the P tones being associated with a frequency, determining a first signal quality of each of the P tones, determining a second signal quality of each of the P tones, and detecting the interferer that occupies the same frequency as one of the P tones based on the respective first signal quality and the respective second signal quality. The first signal quality and second signal quality behave differently when the interferer is present. The detecting the interferer includes determining a discrepancy in the behavior of the first signal quality and the second signal quality.
