Title: Kiyohito Tokuda: Innovator in Signal Processing Technology
Introduction
Kiyohito Tokuda is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of signal processing, particularly in the development of advanced communication technologies. With a total of 5 patents to his name, Tokuda's work has had a lasting impact on the industry.
Latest Patents
One of Tokuda's latest patents is a CDMA receiver with weighted interference cancellation. This innovative technology allows a code division multiple access receiver to estimate symbol values transmitted by different stations by despreading a combined received signal. The receiver weights the estimated symbol values using weighting factors calculated for the different stations. It then respreads the weighted symbol values to estimate the interference from each station and subtracts this estimated interference from the received signal to produce a residual signal. The weighting factors can be derived from the residual signal and are adjusted at intervals based on the rate of fading of the received signal. Another notable patent is related to signal transmission equipment, which ensures that a signal point does not cross the origin of the constellation by selecting appropriate signals for input to the QPSK modulator.
