摘要：
This paper presents a new method that improves the performance of coded cooperation, especially in the error floor region. This method uses a modified repeat-punctured turbo code or double repeat-punctured turbo code with the cooperative scheme, where the modified repeat-punctured turbo code uses a repeater and an interleaver for both the first and second recursive systematic encoders. The analysis and simulation results of the proposed scheme are given and a comparison is made with the conventional turbo coded cooperative diversity scheme and the coded cooperation with repeat-punctured turbo code.
