TRANSMITTING DEVICE, RECEIVER AND DECODER

摘要

PURPOSE: To detect a transmission error and effectively correct it by transmitting a digital signal, without reducing a valid data rate. CONSTITUTION: A deciding circuit 4, a 2nd diciding unit 42 for estimating the bit error rate of decoded information signal 3 and/or 3rd deciding unit 43 for detecting a 3rd error signal e3 for synchronizing the digital signal are provided. These decision units respectively evaluate a sum S, formed from binary values W1...WM in a memory means SR.
