With a total of 2 patents, his work has garnered attention for its innovative approaches to solving complex problems in signal processing.
Latest Patents
Ohama's latest patents include a frequency control device and an information reproduction apparatus. The frequency control device is designed to detect a frame sync pattern and generate frequency information accurately, even when the reproduction signal is not zero-crossed. This device features an oscillation circuit that outputs a clock corresponding to a control signal, a converter that samples an input analog signal based on the clock, and a frequency detection device that identifies sync patterns from the digital signal's changing trend.
The information reproduction apparatus addresses issues related to burst errors. It corrects errors that occur before a synchronization pattern is detected, thereby reducing overall errors. This apparatus includes a bit slip judging section that calculates correction amounts and positions based on phase error signals and synchronization pattern signals. A FIFO control section manages a FIFO buffer to perform bit slip correction, ensuring that errors preceding a detected synchronization pattern are minimized.
