Latest Patents

One of his latest patents is titled "Method of estimating digital audio availability for supplemental audio programs in HD radio broadcast." This invention involves a radio signal processing circuit that includes multiple audio blend channels, an audio decoder, a program selector, and a blending circuit. The audio blend channels are designed to receive digital audio packets for various supplemental audio programs. Each channel features an audio blend buffer and a signal quality metric circuit, which determines an audio quality indicator for the digital audio packets. This indicator helps in assessing the availability of the program based on audio quality, regardless of whether the program is selected for playback.

Another notable patent is the "System and method for synchronous processing of analog and digital pathways in a digital radio receiver." This method processes a digital radio broadcast signal by receiving baseband signal samples at a first sample rate. It adjusts the sample rate based on the difference between the receiver clock and the transmitter clock, producing adjusted baseband signal samples. The method filters these samples to separate the digital and analog components, ensuring they remain synchronous. It also includes separate demodulation of these components to generate both digital and analog output signals.
