Title: John Akira Tani: Innovator in Digital Communications
Introduction
John Akira Tani is a notable inventor based in Vancouver, Canada. He has made significant contributions to the field of digital communications, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of Tani's latest patents is a digitally implemented demodulator. This invention applies a frequency-modulated signal to a limiting amplifier, ensuring that the signal amplitude remains fixed at a constant level. The signal is then undersampled and quadrature demodulated, allowing the demodulator to generate the cross-product of the baseband complex envelope to recover the original modulating signal. Additionally, a digital Frequency Shift Keyed signal can be recovered by applying the recovered signal to a data slicer and a matched filter for improved error resistance.
Another significant patent is a phase-locked loop controller for a frequency hopping radio. This controller is designed for a frequency hopping communications system and utilizes an indirect addressing scheme to access PLL data. It is hardware-implemented, requiring little to no microcontroller processing overhead. The controller facilitates simple synchronization with other units in a communications infrastructure and provides a straightforward interface for implementing dynamic channel allocation methods. An override port allows for external control of the PLL, and the controller can manage auxiliary aspects of system operation, such as powering down a transmitter while changing PLL tuning.
