在三条径的瑞利信道中,对于直接序列扩频:
(1) 请设计DS-CDMA一种具体的码分导引辅助的信道估计方法,接收机分别采用等均益合并、最大比合并。用Simulink进行仿真,测量BPSK的误码率性能,画出比特信噪比与信道估计均方误差的关系曲线,画出比特信噪比与误码率的关系曲线,请解释在误码率为0.01时,两种合并方式所表现的不同的物理意义。
(2) 设频率已经同步,请设计DS-CDMA一种具体的单停顿滑动相关时间同步方法,用Simulink进行仿真(自己编写代码S-Function方式),分析所设计方案的时间同步精度,画出比特信噪比与捕获概率的关系曲线。
(3) 设时间已经同步,请设计DS-CDMA一种具体的频率方法,用Simulink进行仿真(自己编写代码S-Function方式),画出比特信噪比与频率同步误差的关系曲线。

EXIT
本源码包参考英国Southampton大学Robert G. Maunder教授2008年的EXIT charts开源demo,给出了通用(分量码多项式可自定义)并行级联Turbo码的EXIT charts的作图源码。同时可完成迭代轨线、BER等值线的绘制等工作。
由于对于码块长较大的情形仿真需要较长时间,源码包也给出了部分分量码多项式的仿真结果,可直接用于绘图。
源码包还给出了最经典的S.Ten Brink介绍EXIT charts基本原理的参考文献,以及本人对通信系统中迭代译码过程分析技术综述的小论文,希望对大家有所帮助。(This source package comes after Professor Robert G. Maunder s open source demo about EXIT charts in 2008 from University Southampton, UK. It is designed for universal (constituent code generation polynomial can be customized) Parallel
Concatenated Turbo Code EXIT charts. The iterative trajectories and BER contour drawing is also completed in this package. Since the long block case costs a lot of simulation time, some simulation results are included in the package. We also give the most classical introduction to the basic principles of EXIT charts from S. Ten Brink, as well as a document about analysis technologies for iterative decoding process in communication systems. Hope this will help.)
