Latest Patents

Ed Bell holds a patent for a "Carrier-recovery loop with stored initialization in a radio receiver." This invention introduces a carrier-recovery loop designed for receivers in communication systems. The loop features a phase-locked loop (PLL) that utilizes a feedback signal to maintain synchronization with the carrier of a received signal. A key aspect of this invention is the storage of an initializing value of the feedback signal in memory, which is then provided to a digitally controlled recovery oscillator (DCO). This approach allows the recovered signal to reach an initial frequency that closely approximates the carrier frequency, significantly improving the acquisition time for phase lock.
