Abstract
A communication system transmits frames with an arbitrary information length among a plurality of possible information lengths. On receipt of a frame, a receiver performs Viterbi decoding and a CRC operation assuming that the information length of the relavent frame is the same as that of an immediately previous frame. The information length of the frame is detected based on the result of the CRC operation.
