Title: Kazuhiko Nakayama: Innovator in Diversity Reception Technology

Introduction

Kazuhiko Nakayama is a notable inventor based in Ishikawa, Japan. He has made significant contributions to the field of diversity reception technology, holding a total of 3 patents. His work focuses on enhancing reception performance while minimizing power consumption.

Latest Patents

One of Nakayama's latest patents is a diversity receiver and diversity receiving method. The purpose of this invention is to provide a diversity receiver capable of performing diversity reception without depending on moving speed. It also aims to achieve compatibility between reception performance and current consumption. The invention includes a bit error rate calculator that calculates the bit error rate from a demodulation result. Additionally, a switching frequency calculator determines the frequency for alternately switching operations of the diversity reception based on the calculated bit error rate. A switching controller then performs operations to select between two receivers, synthesizing their output signals to produce a synthesized signal.

Another significant patent is a diversity receiving device designed to reduce power consumption while maintaining predetermined received quality. This device makes decisions about executing diversity reception by sensing received quality. It controls the diversity gain and stops the receiving operation of branches with low received quality when the quality exceeds a set value. This innovative approach allows for substantial power savings while ensuring reliable reception quality.
