Abstract

Over the past few years, with the rapid development of satellite communication technology, people have increasingly high standards for the quality of satellite communication. As an ideal code type close to Shannon limit, Turbo code has also been widely used in the field of satellite communication and has become the focus of channel coding research. Turbo code is a parallel concatenated convolutional code. It uses the iterative soft in and soft out decoding method to achieve the performance close to the Shannon limit. First, the basic theory of Turbo code and the related structures of encoding and decoding are introduced in detail, and the causes of Turbo code error floor problem are analyzed. In the process of studying the performance of Turbo codes, different parameters are simulated, such as code length, interleaver length, different iteration times and so on. In addition, a scheme of product code composed of BCH code and Turbo code is proposed to effectively deal with the error floor problem. By analyzing the simulation results, the conclusion of the influence of different parameters on the performance of Turbo codes is obtained, and the error floor problem is effectively improved. By improving the performance of Turbo code, it can be used more widely.
