Latest Patents
One of his latest patents is titled "Receiver having equalizing demodulator and a non-equalizing demodulator and method for controlling the same." This invention comprises a non-equalizing demodulator, an equalizing demodulator, and an output control selector. The non-equalizing demodulator receives a modulated signal and demodulates it to produce a first digital bit stream. The equalizing demodulator also receives the modulated signal, equalizes it, and demodulates it to produce a second digital bit stream. The output control selector selectively delivers one of these digital bit streams based on a predetermined decision criterion, such as bit error rate.
Another significant patent is "Receiver having gain control and narrowband interference detection." This invention generates two metrics: one for controlling the gain of an amplifier and the other for detecting the presence of narrowband interference. These metrics can represent analog-to-digital converter saturation and average signal strength, which are crucial for effective gain control and interference detection.
