Latest Patents

Among his latest patents, Mitchell has developed an apparatus for demodulating digital video broadcast signals. This apparatus comprises data modulated on a plurality of spaced carrier frequencies, featuring a transform circuit and a timing synchronization circuit. The transform circuit is designed to analyze digital sample values, while the timing synchronization circuit ensures synchronization with the symbol periods of the broadcast signal. This system operates in two modes: one for establishing synchronization over a wide timing range and another for fine-tuning synchronization around a specific point.

Another significant patent involves a demodulator suitable for implementation in a single chip. This demodulator converts an input broadcast signal to a frequency low enough for analog-to-digital conversion. It includes components for converting the broadcast signal to digital samples, real to complex conversion, and Fourier transform analysis. The signal processing means also incorporate channel equalization and channel state information generation.
