Latest Patents

One of Laneman's latest patents is titled "Multi-mode decoding for digital audio broadcasting and other applications." This invention discloses techniques for processing received information in a communication system, significantly improving performance in the presence of certain types of interference, such as partial-band interference. In this system, first and second digital sidebands are transmitted on either side of an AM or FM host carrier signal in a hybrid in-band on-channel (HIBOC) digital audio broadcasting (DAB) system. The compressed digital audio information in the sidebands is encoded using an error-correcting code, such as a Reed-Solomon (RS) code. The receiver detects interference within a designated portion of a sideband and employs a fixed-erasure decoding technique if interference is detected. If no interference is found, a hard-decision decoding technique is utilized. This multi-mode approach reduces complexity compared to conventional maximum likelihood decoding and provides a block error flag for error concealment in an audio decoder.

Another significant patent is "Error screening based on code and control information consistency in a communication system." This invention enhances error screening techniques for processing digital audio or other types of information in a digital communication system. It identifies control information associated with a packet of received information and compares it with the decoding requirements of the packet. An error indicator is generated in response to any inconsistencies, such as discrepancies between the packet length indication and the number of bits required for decoding. This invention is particularly well-suited for processing encoded digital audio information in a HIBOC DAB system.
