| 摘 要： | A new concept of q-ary (q = 2') turbo codes and the corresponding decoding aglorithm are presented. With QAM modulations, the proposed algorithm avoids the information loss caused by a pragmatic approach usually used for a binary code to split the channel measurement information into coding bits. So better performance is achieved. Because of the parallel operation property, the decoding can be speeded up by the proposed algorithm. In addition, a method to reduce the average number of iterations is also considered.
