Martin A. Stern 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: 8498350
    Abstract: A wireless radio transceiver system configured to transmit and receive a communications signal waveform having a time division multiple access physical layer structure and which includes a sequence of orthogonal frequency division multiple access symbols. The transceiver provides transmit diversity through space-time coding and the use of orthogonal channel probes from each transmitter. The waveform is packet based and contains a packet header definition that supports local receiver synchronization. Examples of the waveform also incorporate transmission security features.

  • Publication number: 20090262700
    Abstract: A spread spectrum radio frequency communication system includes a Forward Error Correction (FEC) algorithm to encode digital data to provide a plurality of symbol groups, the FEC algorithm using a Reed Solomon FEC code, an interleaving algorithm to map each one of the plurality of symbol groups into a corresponding one of a plurality of coherent sub-bands, and a Walsh encoder to encode each one of the plurality of symbol groups.
