瑞利衰退通道模型，以matlab寫成。這是我用網路上可找到的資源，加以修改，使其更能適應各種不同狀況的模型。(Rayleigh fading channel using Dent model, and my own improvement.)

When scanning in PPI mode, the radar holds its elevation angle constant but varies its azimuth angle. The returns can then be mapped on a horizontal plane. If the radar rotates through 360 degrees, the scan is called a "surveillance scan". If the radar rotates through less than 360 degrees, the scan is called a "sector scan".

matlab实现二维数组的fft变化，得到时域图、幅频域图。(fft change implementation, time domain, frequency domain amplitude, is a two-dimensional array of the FFT changes)

Quadrature amplitude modulation (QAM) is a modulation scheme in which two sinusoidal carriers, one exactly 90 degrees out of phase with respect to the other, are used to transmit data over a given physical channel. One signal is called the I signal, and the other is called the Q signal. Because the orthogonal carriers occupy the same frequency band and differ by a 90 degree phase shift, each can be modulated independently, transmitted over the same frequency band, and separated by demodulation at the receiver. For a given available bandwidth, QAM enables data transmission at twice the rate of standard pulse amplitude modulation (PAM) without any degradation in the bit error ratio (BER).

Planned Scheduling for Economic Power Sharing in a CHP-Based Micro-Grid

将实信号变换为复信号，提取信号幅值、相位角，计算相位同步指数，分析各组信号数据之间的同步稳定性。(The signal is converted into a complex signal, extraction of signal amplitude, phase angle, calculation of phase synchronization index, analysis of stability of synchronization between each signal data.)

里面包含了大量的matlab的应用实例，对初学者来说非常有用(Which contains a large number of matlab application, is very useful for beginners)
