Latest Patents
One of Bagby's latest patents is titled "Method and apparatus for subband signal demodulation in a transponder satellite communication link containing a component of relayed interference." This invention describes a method and apparatus for demodulating a remote-terminal signal located at a subband offset frequency. The process involves transferring digital data to the local-terminal receiver, which is then time-delayed and converted to a narrowband offset-constellation signal. This innovative approach allows for larger interference cancellation factors compared to conventional broadband systems.
Another significant patent is "Method and apparatus for recovering data from a radio signal." This invention addresses the challenges of preamble acquisition and d.c. offset correction in a communications system. By utilizing receiver averaging of sampled values, the system can simultaneously achieve d.c. offset correction and symbol timing acquisition. This method enhances the efficiency of data extraction from a synchronous digital data stream.
