簡單的加密解密算法,可逆與不可逆 數(shù)據(jù)加密: 算法1:(不可逆) 將ASCII表中32~~126中的字符，加密后，顯示為128~~255的字符. 128~~255的字符會讓人看起來頭痛些。。。。。。安全. 當ch[?]的值為偶數(shù)時：ch[?]=255-ch[?]的個位*10-ch[?]的十位 當ch[?]的值為奇數(shù)時: ch[?]=128+ch[?]的個位*10+ch[?]的十位 當ch[?]的值為質(zhì)數(shù)時：ch[?]=128+ch[?]的個位+ch[?]的十位 算法2:(可逆) 當ch[?]的值能被3整除時:ch[?]-=2，否則ch[?]-=3

This is GPS Matlab findPreambles finds the first preamble occurrence in the bit stream of each channel. The preamble is verified by check of the spacing between preambles [6sec] and parity checking of the first two words in a subframe. At the same time function returns list of channels, that are in tracking state and with valid preambles in the nav data stream.

在VB中把中文轉(zhuǎn)化成Unicode碼 首先介紹一下VB中的兩個函數(shù):ChrW()和AscW().對于Chr()和Asc()函數(shù)大家一定很熟悉,對于ChrW()和AscW()可能會比較生疏一點. ChrW 函數(shù)返回包含 Unicode 的 String，若在不支持 Unicode 的平臺上，則其功能與 Chr 函數(shù)相同 AscW 函數(shù)返回 Unicode 字符代碼，若平臺不支持 Unicode，則與 Asc 函數(shù)功能相同。
