基于BP神经网络的字符识别算法源代码，包括网络仅值训练方法，训练是通 过调用34个字符文件夹，识别率达到99.8 。(BP neural network-based character recognition algorithm source code, including the value of the network only training methods, training is by calling the 34-character file folders, the recognition rate of 99.8 .)

该程序是基于时间延迟求和的波束成形算法的实现，根据是结果来看有很好的效果(The program is based on the sum of the time delay beamforming algorithm, based on results, there is a good effect)
