支持DVB-S,DVB-T,DVB-C的系统前端加扰和解扰过程，请注意加扰与加密不同，本程序包实现的是纯粹的加扰和解扰过程，不对KEY进行加密传输。要求输入测试文件时，请按照C语言的文件访问要求输入，如key.txt表示你要使用的KEY放在了名为key的txt文件中，不可写成“key.txt”。-To support the DVB-S, DVB-T, DVB-C system front-end process of scrambling and descrambling, please no

The paper presents an in situ parameter estimation method to determine the equivalent circuit parameters of the three-winding transformer (TWT). The suggested method also estimates geometrically a complex parameter that is mutual leakage between

Implement Diffie-Hellman Key exchange protocol and demonstrate that at the end, both person will have a common Key. Do the following: 1. Set a variable p ( e.g. p = 37) and g (e.g. g = 5). 2. Generate a, a random number mod p. Now generate A,
