substitution cipher is the method of encoding in which unit of plain text are replaced by cipher text. Monoalphabetic cipher uses a fixed message over entire message.A monoalphabetic cipher uses fixed substitution over the entire message.The monoalphabetic substitution takes a letter of an alphabet and substitutes it with another letter, this way a ciphertext is generated. The way of converting is fixed. A character of the plaintext will be replaced by the same ciphertext character, during the entire ciphertext. There is no additional key. The only way of security is to keep the substitution-table secret.
A popular example for the monoalphabetic substitution is the caesar cipher.

说明： 1， 自动去除导频，空子载波的simulink模块
2， 接下来是转二进制的模块（集成在解交织解卷积模型里，用一个Interger2Bit实现）
3， 然后是解交织解卷积模型—deconv. 负责解交织和解卷积
4， 再就是解RS解随机化模型—decode_new. 负责解RS解随机化
5， decode.m文件： 负责主程序的运行，实现参数的输入和修改，支持各种调制编码方式
(1, automatically remove the pilot, take advantage of the simulink Carrier Module 2, followed by a binary switch module (integrated in deinterleave deconvolution model, with a Interger2Bit achieve) 3, followed by deconvolution model deinterleave-deconv . responsible for reconciliation deinterleave convolution 4, Then solution RS solution model random-decode_new. responsible solution RS solution randomized 5, decode.m documents: the main program is responsible for the operation, to achieve input and modify parameters to support a variety of modulation encoding)
