Title: Innovations of James L. Porter
Introduction
James L. Porter is a notable inventor based in Oklahoma City, OK (US). He has made significant contributions to the field of technology, holding a total of 5 patents. His work primarily focuses on advancements in receiver technology, showcasing his expertise and innovative spirit.
Latest Patents
One of his latest patents is a receiver that features both an equalizing demodulator and a non-equalizing demodulator. This invention includes a method for controlling the output of these demodulators. The non-equalizing demodulator receives a modulated signal and demodulates it to produce a first digital bit stream. Meanwhile, the equalizing demodulator processes the same modulated signal to generate a second digital bit stream. The output control selector then selectively delivers one of these digital bit streams based on a predetermined decision criterion, such as bit error rate.
Another significant patent is a frame synchronizer designed for use in receivers. This device processes an encoded signal received from a transmitter. It includes a conjugation unit, a delay unit, and a multiplier that work together to produce a first product signal. This signal is then used to generate a second product signal, which is accumulated over multiple bit times to create an accumulated signal. This signal helps correct time and frequency offsets between the receiver and the transmitter, enhancing synchronization.
