在数据加密和数据压缩中常需要对特殊的字符串进行编码。给定的字母表A 由26 个小 写英文字母组成A={a,b,…,z}。该字母表产生的升序字符串是指字符串中字母按照从左到 右出现的次序与字母在字母表中出现的次序相同,且每个字符最多出现1 次。例如, a,b,ab,bc,xyz 等字符串都是升序字符串。对于任意长度不超过6 的升序字符串,迅速计算出它在上述字典中的编码。

Matlab is an ideal tool for simulating digital communications systems, thanks to its easy scripting language and excellent data visualization capabilities. One of the most frequent simulation tasks in the field of digital communications is bit-error- rate testing of modems. The bit-error-rate performance of a receiver is a figure of merit that allows different designs to be compared in a fair manner. Performing bit-error-rate testing withMatlab is very simple, but does require some prerequisite knowledge
