Alfred W. Pietzold, III 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).

  • Field programmable radio frequency communications equipment including a configurable if circuit, and method therefor
    Patent number: 6343207
    Abstract: A system and method for providing a field configurable radio frequency communication system including an intermediate frequency digital signal processing circuit therefor. The intermediate frequency digital signal processing circuits includes digital transmitter and receiver circuit paths, a digital baseband circuit, control registers and an interface circuit. The transmitter and receiver circuit paths and the baseband circuits include digital processing circuits that are configurable by commands provided to the control register via the interface circuit to select the transmitter or receiver mode of operation, to select the signaling scheme of waveform employed, to configure the signal processing functions of the transmitter or receiver circuit paths, and to select the use of any of a plurality a baseband signal processing functions.

  • Reconfigurable radio system architecture
    Patent number: 6091765
    Abstract: A system and method for providing a digital field configurable radio frequency communication system that can be configured into a transmitter, or a receiver, to function with a plurality of signaling schemes, such as, AM, AME, A3E, H3E, J3E, CW, SSB, M-PSK, QAM, ASK, angular modulation, including FM, PM, FSK, CMP, MSK, CPFSK etc. The system includes a non volatile memory that is adapted to receive and store instructions for configuring the system. A user selects the mode of operation and the signaling scheme, and instructions and software are downloaded from the memory into the system and configure the system as selected by the user.
