调制的代码，包含FSK,ASK等多种调制方式。(Modulation code, including FSK, ASK modulation, etc..)

本算法是一种变步长的LMS算法，可以适用于智能算法等相关技术中(this algorithm is about a variable step-size LMS adaptive filter,and can be implied in samrt antenna)

FDTD方法的书，书中有代码，很不错，可以看看(FDTD)

自适应滤波器的特点是自动调节自身的冲激响应,达到最优滤波,此算法适用于平稳和非平稳随机信号,并且不要求知道信号和噪声的统计特性。(Adaptive filter is characterized by automatic adjustment of its own impulse response, the optimal filtering, this algorithm applied to a smooth and non-stationary random signal, and does not demand to know the signal and noise is investigated.)
