With a total of four patents to his name, Caldwell has developed advanced technologies that enhance data transmission and decoding processes.

Latest Patents

Caldwell's latest patents include a "Digital Packet Data Trellis Decoder" and a "Code Sequence Detection in a Trellis Decoder." The Digital Packet Data Trellis Decoder features an adaptive trellis decoder system that utilizes a state transition trellis with a predetermined number of states for decoding interleaved data packets. This system is designed to handle data interruptions and transitions between different types of data, ensuring efficient decoding in response to synchronization signals. The decoder can reset to a predetermined state based on detected synchronization intervals, allowing it to decode re-aligned data effectively.

The second patent, Code Sequence Detection in a Trellis Decoder, introduces an adaptive trellis decoder that can seamlessly switch between multiple operational modes. This decoder employs a code sequence detection system that identifies codes in input interleaved packet data, significantly reducing latency between input and output. It processes video data in groups of interleaved trellis encoded data packets and includes a traceback network that identifies antecedent trellis states based on decision data associated with state transitions.
