Masahiro Tachibana is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of data transfer technology, holding a total of 7 patents. His innovative work has paved the way for advancements in communication apparatuses and signal detection methods.

Latest Patents

Tachibana's latest patents include a data transfer circuit and a communication apparatus. The data transfer circuit features a memory that writes data in synchronization with a first clock and reads it out with a second clock. It incorporates a clock generation circuit that generates the second clock by multiplying a reference clock by a rational number N. Additionally, it includes a frequency error estimation circuit that estimates the frequency error between the two clocks based on the pointer difference. The adjustment circuit outputs an adjustment multiple ΔN, enhancing the accuracy of data transfer.

Another notable patent involves a known signal detection method. This method utilizes Fourier transform on a reception signal to derive a first calculation value and performs a similar process on a known signal to obtain a second calculation value. By dividing the first calculation value by the second, a third calculation value is achieved. An inverse Fourier transform is then applied to this value to detect the maximum amplitude and its corresponding sample point, allowing for the identification of the known signal's position within the reception signal.
