Title:
TRANSMISSION DEVICE, AND PEAK SUPPRESSION METHOD
Document Type and Number:
Japanese Patent JP2009159055
Kind Code:
A
Abstract:
To provide a peak suppression device conforming to respective signal quality specifications in amplifying signals each requiring distinct signal quality by a single transmission amplifier by converting the signals to multicarriers.
This peak suppression device includes: a peak suppression part reducing peaks of transmission signals of respective channels in order to reduce the transmission signal peaks by an appropriate peak suppression amount according to required performance; an error measurement part calculating an error from a feedback signal of the transmission signal; and a peak control part comparing the calculated error with a target value to control the suppression amount of a peak limiter to set the error at the target value.
