PLL_2nd

说明：  详细介绍了宽带无线通信中OFDM的基本原理和关键技术。(The book describs the fundamental theory and key technology of OFDM in detail.)

传输参考TH-PPM调制超宽带信号功率谱密度(transmission reference TH-PPM modulated ultra-wideband signal power spectral density)

说明：  反正切函数的变步长算法,能实现反正切函数的变步长的仿真！(Arc tangent function, variable step-size algorithm)

图像的锐化和均衡，图像处理中最基本的两个处理方法，用matlab实现，算法简单，易懂(Image sharpening and balanced, the two approaches are the most basic image processing using matlab algorithm is simple and easy to understand)

利用matlab软件设计并仿真下面的无线通信系统。模拟信源为单音频信号。模拟调制方式为DSB。信道为多径信道（仿真中2径），信道中噪声为加性高斯白噪声。采用相干解调接收。画出了解调器输出端性能曲线与点信噪比SNR的关系。 (Software design and simulation using matlab the following wireless communication systems. A single analog audio signal source. Analog modulation of DSB. Channel multi-path channel (simulation 2 diameter), channel noise is additive white Gaussian noise. The use of coherent demodulation receiver. Draw the output of the demodulation performance curve and the point of the relationship between signal to noise ratio SNR.)

This is a function that simulate the Alamouti Space-Time scheme and plot a BER vs SNR graph.
