Abstract
On a transmitter side, a known bit inserting section,inserts a known bit having a predetermined length at a predetermined position of transmitting data, and a tail bit inserting section,inserts a tail bit thereto so as to generate frame data. Then, a frame length detecting section,detects a length of frame data, a convolutional coding section,convolutional codes the frame data, and a dummy bit inserting section,inserts a dummy bit to the frame data so as to obtain a transmitting signal. On a receiver side, a decoding section,divides a receiving signal into a convolutional coded portion, including a head portion to a tail of a known bit, and a subsequent portion so as to perform decoding on a receiver side. Then, an unnecessary bit removing section,removes the known bit, the tail bit, and the dummy bit from the decoded data.
