Abstract:
(EN) An improved turbo code encoding method and an encoder therefor are disclosed. The encoder in the present disclosure may comprise four delayers. Also, the encoder may determine a circulation state through pre-encoding and, based on the circulation state, generate a turbo code having a tail-biting structure. Furthermore, the encoder may comprise a switching circuit and work just like the conventional LTE turbo code encoders by turning off the switching circuit.
(FR) L'invention concerne un procédé de codage de turbo-code amélioré et un codeur associé. Le codeur selon la présente invention peut comprendre quatre retardateurs. En outre, le codeur peut déterminer un état de circulation par précodage et, sur la base de l'état de circulation, générer un turbo-code ayant une structure en boucle. De plus, le codeur peut comprendre un circuit de commutation et fonctionner comme les codeurs turbo-codes LTE classiques en éteignant le circuit de commutation.
(KO) 개선된 터보 코드 부호화 방법 및 이를 위한 부호화기가 개시된다. 본 개시물의 부호화기는 4개의 지연기를 포함할 수 있다. 또한, 부호화기는 사전 부호화를 통하여 순환 상태를 결정하고, 순환 상태에 기초하여 테일 바이팅 구조를 갖는 터보 코드를 생성할 수 있다. 또한, 부호화기는 스위칭 회로를 포함하고, 스위칭 회로를 턴-오프함으로써 종래의 LTE 터보 코드 부호화기와 동일하게 동작할 수 있다.
