With a total of 7 patents to his name, Eguchi's work has had a lasting impact on the efficiency and performance of communication technologies.
Latest Patents
One of Eguchi's latest patents is a receiver designed for receiving a spectrum dispersion signal. This innovative receiver reduces power consumption during suspension periods of intermittent receiving operations. It achieves this by utilizing a low-power timer to monitor the suspension period, allowing components such as the VC-TCXO, reference signal group generation, and receiving units to be turned off. The modem unit is set to a sleep state during this time. Upon resuming receiving operations, a high-accuracy timer is activated to count a time period, during which part of the received signal is stored. The PN code phase of the stored data is then calculated to obtain an indication value for phase deviation. State vectors for short and long codes, as well as a further reception time, are calculated based on this indication value. When the high-accuracy timer counts the time period and produces 0V(d), the demodulation operation by rake demodulation, demultiplexing, and descrambler units is initiated and continues throughout the reception time.
