Title: Ryuichi Okazaki: Innovator in Digital Broadcasting Technology

Introduction

Ryuichi Okazaki is a notable inventor based in Machida, Japan. He has made significant contributions to the field of digital broadcasting technology. With a focus on enhancing the efficiency and performance of broadcast receivers, Okazaki has secured a total of 2 patents.

Latest Patents

Okazaki's latest patents include a BS digital broadcast receiver and an AM data multiplexing modulation apparatus. The BS digital broadcast receiver is designed to operate without an 8PSK-demapper and minimizes the number of delay circuits for Trellis encoding. It utilizes a Viterbi-decoder to decode a QPSK baseband signal based on the reception signal point position. The output is then convolution-reencoded, ensuring efficient processing of phase error data for carrier reproduction.

The AM data multiplexing modulation apparatus allows for the multiplexing of a digital signal to an AM modulation signal without negatively impacting the AM sync detection output. This innovative design incorporates an AM modulator and orthogonal modulators to effectively manage the modulation process, resulting in a seamless output.
