摘要： A method and apparatus for Convolutional Turbo Coding (CTC), and an apparatus for a turbo encoder are provided. The method for CTC includes the steps of encoding information bits A and B using a constituent encoder, and outputting parity sequences Y1 and W1, interleaving the information bits A and B using a CTC interleaver to obtain information bits C and D, and encoding the interleaved information bits C and D using the constituent encoder to obtain parity sequences Y2 and W2, interleaving the information bits A and B, the parity sequences Y1 and W1 and the parity sequences Y2 and W2, respectively, wherein the bits in at least one of a bit group constituted of the information bits A and B, a bit group constituted of the sequences Y1and W1, and a bit group constituted of the sequences Y2 and W2 are alternately mapped to bits of constellation points with high reliability and low reliability and puncturing the interleaving result to obtain the encoded bit sequences.
