Abstract
A mobile communication terminal which receives convolutionally encoded data that is convolutionally encoded information of a speech channel transmitted from a base station and detects a transmission bit rate selected at the base station by decoding the data. The mobile communication terminal comprises a rate estimation unit which estimates the transmission bit rate selected at the base station and outputs an estimated transmission bit rate, a decoding unit which decodes the convolutionally encoded data transmitted from the base station and outputs decoded data and predetermined types of results of decoding, a convolutional re-encoding unit which convolutionally re-encodes the decoded data and outputs re-encoded data, and a rate detection unit which detects whether the estimated transmission bit rate is correct or not based on the decoded data and the predetermined types of results of decoding.
