通信系统解调中载波锁相环的设计

说明：  实现Polar码编码译码，SC译码，简单实用，运行速度快(Polar MATLAB include encode and decode useful and simple)

说明：  4. 试说明卷积编解码的工作原理： (1) 使用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编码、译码全部是自己编写代码(S-Function方式)，不是调用Simulink的已有编码、译码函数。 (2) 请在加性白高斯噪声信道中，画出比特信噪比与误码率的关系曲线。(4. Try to explain the working principle of convolutional codec: (1) Simulink was used to simulate convolutional coding, and Viterbi decoding method was used for decoding. The coding and decoding were all written by oneself (s-function method), rather than calling the existing coding and decoding functions of Simulink. (2) in the additive white gaussian noise channel, please draw the curve of the relationship between bit signal-to-noise ratio and bit error rate.)

整个OFDM的matlab仿真代码，使用16qam调制，还有word的文档，讲解很细(The OFDM matlab simulation code, the use of 16 qam modulation, and word document, very fine )

iEEE 207 标准 信道编码相关 卫星通信(iEEE 207 standard channel coding satellite communications)

给出了分数阶傅里叶变换的具体实现程序，阶数可调。该程序实现是根据一篇通信学报上的论文做的。同时提供了OFDM系统在不同信道估计技术下的误码率以及多径信道下的性能。对于想研究基于分数阶傅里叶变换的OFDM系统的人有一定帮助。(The codes for fractional fourier transform (frft) and its inverse way are given according to a published paper in Journal of Communication. The power is adjustable. In addition, two programms of OFDM system simulation under different channel estimate technique and multipath are offered. Therefore, such file packet is of use for those who have interests in studying OFDM based on frft)

说明：  DRM 外辐射源雷达的杂波抑制算法代码，LMS RLS ECA 有问题。(The code of clutter suppression algorithm for DRM external emitter radar has some problems with LMS RLS ECA.)
