设A和B是长度相同的2个字符串。A和B的距离定义为相应位置字符距离之和。2个非空格字符的距离是它们的ASCII码之差的绝对值。空格与空格的距离为0；空格与其它字符的距离为一定值k。 字符串A的扩展是在A中插入若干空格字符所产生的字符串。在字符串A和B的所有长度相同的扩展中，有一对距离最小的扩展，该距离称为字符串A和B的扩展距离。 对于给定的字符串A和B，试设计一个算法，计算其扩展距离。

回溯（b a c k t r a c k i n g）是一种系统地搜索问题解答的方法。为了实现回溯，首先需要为问题定义一个解空间（ solution space），这个空间必须至少包含问题的一个解（可能是最优的）。在迷宫老鼠问题中，我们可以定义一个包含从入口到出口的所有路径的解空间；在具有n 个对象的0 / 1背包问题中（见1 . 4节和2 . 2节），解空间的一个合理选择是2n 个长度为n 的0 / 1向量的集合，这个集合表示了将0或1分配给x的所有可能方法。当n= 3时，解空间为{ ( 0 , 0 , 0 )，( 0 , 1 , 0 )，( 0 , 0 , 1 )，( 1 , 0 , 0 )，( 0 , 1 , 1 )，( 1 , 0 , 1 )，( 1 , 1 , 0 )，( 1 , 1 , 1 ) }。

This code was used for making the practical measurements in section 2.3 of my thesis. This Matlab code allows an OFDM signal to be generated based on an input data file. The data can be random data, a grey scale image, a wave file, or any type of file. The generated OFDM signal is stored as a windows wave file, allowing it to be viewed, listened to and manipulated in other programs. The modified wave file can then be decoded by the receiver software to extract the original data. This code was developed for the experiments that I performed in my honours thesis, and thus has not been fully debugged. This is the original code developed for the thesis and so has several problems with it. The BER performance given by the simulations is infact Symbol Error Rate.
