Title:
TAIL-BITING CONVOLUTIONAL CODE ENCODING METHOD, DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/000196
Kind Code:
A1
Abstract:
The embodiments of the present application provide a tail-biting convolutional code encoding method, device and system, relating to the field of communications. Regardless of the length of an inputted information bit stream, the invention may realize low code-rate encoded tail-biting convolution code with high encoding gain, improving the communication reliability. The method specifically comprises: acquiring an information bit stream; encoding the information bit stream by means of a tail-biting convolutional code encoder, to acquire n check bit streams; when n is greater than or equal to 4, a mother code generated polynomial of the tail-biting convolutional code encoder comprising at least one piece of the following information: G3=137, G4=115, G5=173, G6=127, G7=145, G8=157 or 167, G9=135, G10=175, G11=113 or 151; Gm being the octal representation of the mother code generated polynomial of the (m+1)th check bit stream.
