Summary: | The objective of the present invention is to provide a method of encoding regular texts to increase the level of security while transmission is easier and a device for generating encoded texts. According to an embodiment, a transmitting device in the present invention includes: a first encoder for encoding regular text data depending on the valid code rate (Re) to output encoded text data; and a second encoder for encoding a first encoding block, corresponding to the encoded text data, to output a second encoding block. The Re is defined as Re=R / (1-Rpunc), wherein R represents the code rate, while Rpunc represents the puncturing rate. The first encoding block includes Zp x Rs x 2n bit, while the second encoding block includes Zp x 2n bit, wherein n represents the number of bits of the regular text data, while Zp represents the lifting factor and Rs represents the SLSS code rate.
본 발명의 다양한 실시 예에 따른 송신 장치는, 일반 텍스트 데이터를 유효 부호율(Re)에 따라 인코딩하여 암호화 텍스트 데이터를 출력하는 제1 인코더와, 상기 암호화 텍스트 데이터에 대응하는 제1 인코딩 블록을 인코딩하여 제2 인코딩 블록을 출력하는 제2 인코더를 포함하고, 상기 유효 부호율(Re)은, Re=R/(1-Rpunc)에 의해 정의되며, 여기서 R은 부호율을 나타내고, Rpunc은 펑처링율을 나타내며, 상기 제1 인코딩 블록은, Zp x Rs x 2n 비트를 포함하고, 상기 제2 인코딩 블록은, Zp x 2n 비트를 포함하며, 여기서 n은 상기 일반 텍스트 데이터의 비트 수를 나타내고, Zp는 리프팅 인자를 나타내며, Rs는 SLSS 코드율을 나타내는 것을 특징으로 한다. |
