摘要：A coding device capable of improving the coding efficiency and a decodingdevice for decoding a code sequence generated by the coding device are provided. In thecoding device, for each of the possible block combinations obtained when dividing a
frame, a coding unit encodes each block in the frame block by block at different bit rates,and at the same time, the coding unit decodes the resultant code sequences related tothe frame. A calculation unit calculates the error powers of the decoded signals and theinput signal. A determination unit selects a code sequence that makes the average bitrate in coding the frame not higher than a specified value and the corresponding errorpower a minimum. This selected code sequence is output.
