Latest Patents

Yoshida holds a patent for a "Transmitter for suppressing a variation in input level of a multicarrier signal." This innovative transmitter is designed to averagedly suppress variations in the input level of an amplifier according to the variations in carrier level. The transmitter includes several key components: an input power calculation section that calculates the mean input power of each carrier, an output power calculating section that determines the mean output power of each carrier after the carrier band is limited, and a monitoring section that identifies the carrier with the maximum mean input power. This section also acquires the maximum value, determines the ratio of mean input power to mean output power, and calculates level control information. Finally, a signal level adjusting section adjusts the level of a multicarrier signal by multiplying the level control information outputted from the monitoring section.
