摘要： PROBLEM TO BE SOLVED: To insert a dummy bit into a information bit so that decoding error is effectively reduced.SOLUTION: In the transmission method of a communication system, the information bit in which a dummy bit is inserted is organized and encoded, and the organized code in which the dummy bit has been deleted is transmitted, and then the dummy bit that has been deleted by the transmission side is inserted into the received organized code, for decoding, at the receiving side. Based on a specified encoding rate, transmission rate, and a bit length for determining transmission rate, the size of a dummy bit that is inserted into the information bit is determined. If the total size of the information bit and the dummy bit is larger than a specified size, the information bit is divided into code blocks. A dummy bit is inserted as a predetermined pattern into respective information bits that have been divided. The information bit into which the dummy bit has been inserted is organized and encoded. The dummy bit is deleted from the organized bit to generate an organized code, and then the organized code is transmitted.

摘要： PROBLEM TO BE SOLVED: To solve a problem in a conventional retransmission control method that deteriorates the transmission efficiency due to unnecessary retransmission when the correctness of a received packet cannot be judged within a prescribed time because the conventional method requires the return of acknowledgement / negative-acknowledgement (ACK / NAK) of a reception apparatus within the prescribed time and a discrimination processing amount as to whether or not the received packet is correct is constrained by this time limit in the case of transmitting the packet subjected to error detection coding from a transmission apparatus to the reception apparatus. SOLUTION: The reception apparatus detects an error from a received packet and corrects the error at the same time, transmits the NAK when the reception apparatus cannot correct the packet within a prescribed time, but continues the error detection correction processing after that, returns the ACK when the apparatus can correct the packet to suppress the frequency of transmission of retransmission packets thereby carrying out efficient re-transmission control.
