Title: Jim Snell: Innovator in Digital Data Radio Technology
Introduction
Jim Snell is a notable inventor based in Palm Bay, FL (US). He has made significant contributions to the field of digital data radio technology, holding a total of 5 patents. His work focuses on enhancing the quality and efficiency of data signal reception.
Latest Patents
One of Jim Snell's latest patents is a "Short burst acquisition circuit and method for direct sequence spread." This invention involves a digital data radio receiver that evaluates a data signal preamble received on an antenna. The receiver determines frequency offsets from a desired frequency for each symbol in a block of symbols in the preamble. It assesses the variance of these frequency offsets and the average magnitude of the symbols to evaluate whether the preamble is noise and to assess reception quality. In a two-antenna diversity receiver system, these evaluations can be compared to select the antenna with the best reception.
Another significant patent is the "Method of estimating signal quality in a DPSK demodulator." This method estimates signal quality in a radio demodulator by sampling a phase-only portion of each symbol in the input stream. It determines phase errors for each sample and calculates a signal quality estimate from these errors. This estimate can be derived from symbols in the preamble or the data signal that follows.
