Abstract
Received quality detecting section 108 detects a received quality, bit determining section 111 determines whether a TPC bit is 0 or 1, amplitude reading section 112 reads a ratio of an amplitude of a signal other than the TPC bit and an amplitude of the TPC bit, accumulating section 113 determines an increase or decrease of transmit power and an amount of the increase and decrease of the transmit power using a symbol of the TPC bit for the increase or decrease, and an amplitude ratio for the amount of the increase and decrease to instruct to transmission amplifier 104, and multiplying section 114 multiplies the amplitude of the signal other than the TPC bit by a correction value corresponding to the received quality to determine the amplitude of the TPC bit.
