  • Coherent synchronization and framing in a digital television receiver
    Patent number: 8724759
    Abstract: The current application is directed to maintaining the correct number of symbols in a protocol frame in a digital communications receiver, to prevent catastrophic failure due to dynamic multipath or cycle slips. Timing recovery and framing are coherent, facilitated by placing channel estimation directly into a larger timing recovery loop.
    Type: Grant

  • Simplified data interface protocol for digital television receiver
    Patent number: 8643775
    Abstract: Certain embodiments of the present invention encapsulate a variety of data, for example, FIC data, together with ATSC-M/H Service data, into a single IP stream, to simplify the interface between demodulator and media processor. A single data interface protocol within the receiver can then be used, facilitating integration.

  • LEAST SQUARES MATRIX COMPRESSION AND DECOMPRESSION IN A DIGITAL TELEVISION RECEIVER
    Publication number: 20120281145
    Abstract: The current application is directed to reducing the implementation cost of least squares (LS) channel estimation in a digital communications receiver. An inverse correlation matrix is compressed on a per-diagonal basis for low cost storage in the receiver. The inverse correlation matrix is decompressed and utilized online on a per-diagonal basis.
