Latest Patents

Takahiko Terakado holds a patent for a "Radio receiver for use in the reception of digital multiplexing signals." This invention addresses the challenges faced when a received multi-level orthogonal amplitude signal is not synchronized with a local carrier frequency signal. The digital multiplexing radio receiver is designed to recognize adaptively-equalized data within a specified area on the phase plane of Ich and Qch orthogonal coordinates. The receiver effectively controls the amplification of Ich and Qch demodulated signals to a fixed level based on the data present in this specified area. Additionally, it adjusts the phase of the local carrier frequency signal and manages tap coefficients of an adaptive transversal filter to equalize the received multi-level orthogonal amplitude signal. This innovation allows the digital multiplexing radio receiver to quickly and stably return to a synchronous mode, ensuring reliable signal reception.
