Latest Patents

One of Muratani's latest patents is the "Adaptive Phase Lock Loop System." This invention features a phase detector, a loop filter, a digital voltage-controlled oscillator (VCO), an initial phase difference calculator, a center frequency difference calculator, and an input buffer memory. In the initial training mode, the system searches for the optimum initial phase and center frequency of the VCO to achieve a lock-in state for the input signal stored in the buffer memory. The system estimates the initial phase difference and center frequency difference through repetitive calculations, ensuring optimal performance. In the normal operation mode, the PLL operates as a conventional phase lock loop, maintaining a phase lock between the VCO output and the input signal.

Another significant patent is the "Hybrid Modulation Satellite Communication System." This system includes multiple small earth stations, a relay earth station, and a satellite. It employs primary modulation of the carrier wave for information transmission, while the operation status of each small earth station is transmitted through secondary modulation. The primary modulation can be BPSK or multiphase PSK, while the secondary modulation may include PSK, ASK, or FSK. The relay earth station adjusts the transmit power to ensure that the receive signal quality at the small earth stations meets desired criteria, regardless of rain attenuation.
