中文摘要：

串行级联连续相位调制（SCCPM）是一类具有较高功率利用率和频谱利用率的恒包络级联编码调制方式。本文研究了采用符号交织器的 SCCPM 系统。与传统的比特交织方案相比，符号交织 SCCPM 系统在收敛门限上可以获得改善，但错误平层更高。通过理论分析和仿真得出系统的各个参数，包括外码、迭代次数、交织长度、基带成形脉冲对系统性能的影响，最后得出了符号交织SCCPM 系统的一些参数设计原则。

英文摘要：

Serially concatenated continuous phase modulation（SCCPM） is a kind of constant envelope concatenated coding and modulation with high power efficiency and bandwidth efficiency.SCCPM with symbol-wise interleaving is studied in this paper.Compared with the traditional bit-wise interleaving scheme,SCCPM with symbol-wise interleaving has a better performance in convergence threshold but a higher error floor.The influence of system parameters such as outer code,iteration number,interleaver length,baseband shaping pulse on the system performance is given through theoretical analysis and simulation.Finally this paper presents some design rules for SCCPM with symbol-wise interleaving.
