Latest Patents

One of his latest patents is titled "Interpolation processing for enhanced signal acquisition." This invention relates to methods and systems for enhanced signal acquisition through cross-ambiguity function (CAF) interpolation. The invention provides methods for generating a second CAF with a higher sample per chip rate by interpolating a first CAF generated using a low input sampling rate. This approach significantly reduces the cost and complexity of initial synchronization processing at the receiver. Additionally, coherent and non-coherent interpolation methods are provided for time and frequency CAF interpolation, along with low-cost implementations and associated CAF peak detection methods.

Another significant patent is the "System for direct acquisition of received signals." This invention describes signal processing architectures for the direct acquisition of spread spectrum signals using long codes. The techniques achieve a high level of parallelism by employing code matched filter banks and other hardware sharing methods. In this embodiment, upper and lower sidebands are treated as independent signals with identical spreading codes. The invention includes cross-correlators that compute parallel short-time correlations of received signal samples and replica code sequence samples, utilizing discrete-time Fourier analysis for cross-correlation values.
