本文件里面有几个基于MUSIC算法的DOA估计。可以帮助新手熟悉过程。(Based on this document, there are several MUSIC DOA estimation algorithm. You can help the novice familiar with the proces)

该报告详细讲述了优化算法的原理，数学模型，实现方法，对于PSO的初学者将会大有裨益。(The report describes in detail the principle of optimization, mathematical models, implementation methods, for the PSO will be of great benefit to the beginner.)

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.
