Title: Tetsurou Imai: Innovator in Receiving Technology
Introduction
Tetsurou Imai is a notable inventor based in Yokosuka, Japan. He has made significant contributions to the field of telecommunications, particularly in the development of receiving apparatuses and methods. With a total of 2 patents to his name, Imai's work has advanced the technology used in downlink signal reception.
Latest Patents
Imai's latest patents include a "Receiving Apparatus and Receiving Method" and a "Receiving Device and Radio Quality Calculation Method." The first patent describes a receiving apparatus designed to receive a downlink signal where pilot symbols are mapped discontinuously. This apparatus features a unit that extracts reference signals from the downlink signal, which is Fourier transformed. It also includes a unit that generates a first signal with a specific window size and performs an inverse Fourier transform on the reference signals. Additionally, it divides the first signal into multiple signals to extract a signal within a second window, ultimately calculating received power based on the generated third signal.
The second patent focuses on a reception device that calculates radio quality in a downlink using multiple pilot symbols transmitted from a base station. This device includes a correlation calculation unit that computes correlation values between pilot symbols on either the time or frequency axis. If the correlation value exceeds a predetermined threshold, the radio quality calculation unit assesses the downlink radio quality based on the reception quality of the pilot symbols.
