Title:
COMMUNICATION SYSTEM AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/044765
Kind Code:
A1
Abstract:
Provided are a communication system and a communication method which can greatly reduce the implementation scale and delay time in the performance of tail-biting convolution encoding with a large encoding size. In the communication system and the communication method: a tail-biting preprocessing unit 101 of a transmission-side communication device 100a generates an input bit sequence by adding a header portion of a bit sequence to be encoded to the end of the bit sequence; a convolution encoding unit 102 performs error correction encoding on the input bit sequence with a convolution encoder, deletes the header portion of the error correction encoded bit sequence, and generates a transmission data sequence in which the tail-biting convolution encoded original header portion is placed at the end; and a reception-side communication device 100b performs error correction on received data.
