Abstract

The present application discloses a turbo code decoder, soft input and soft output method, electronic equipment, and a computer-readable storage medium. The turbo code decoder includes: a system buffer for receiving a system bit signal and a first address output by a bidirectional interleaver signal; the first parity buffer is used to receive the first error detection bit signal and the second address signal output by the bidirectional interleaver; the second parity buffer is used to receive the second error detection bit signal and the second address signal; the second The output signals of the first parity buffer and the second parity buffer are selected and output to the soft input and soft output unit after being passed through the data selector; the output signal of the system buffer is added to the decoded signal output by the bidirectional interleaver, respectively sent to the first shift register and the soft input and soft output unit; the output signals of the first shift register and the soft input and soft output unit are sent to the threshold comparator after difference. The application effectively reduces the product cost and improves the product economic benefit.

Description

technical field [0001] The present application relates to the technical field of data encoding and decoding, and in particular, to a turbo code decoder, a soft input and soft output method, an electronic device, and a computer-readable storage medium. Background technique [0002] In general electronic products, there are many methods for data transmission, and there are different communication protocols. Many encoding and decoding functions are used. Different encoding and decoding methods are realized through different algorithms. Therefore, the improvement and introduction of algorithm methods has become an important research direction. [0003] Turbo code is a forward error correction coding technique in information theory. Turbo code is the first practical code that can approach the Shannon limit. It has excellent performance under low signal-to-noise ratio conditions and is widely used in 3G / 4G mobile communications (such as UMTS and LTE), deep space satellite communi...
