本设计对滑模变结构控制进行相关的研究,以Buck型变换器的控制为重点,通过对基本型的三阶滑模变结构控制方法、改进型的滑模变结构控制方法和基于等效理论的定频滑模控制方法的仿真,调节控制系统的参数,最后完成仿真，实验波形验证理论。(The design of the variable structure control studies related to control Buck Converter for emphasis, through the basic third-order sliding mode variable structure control, sliding mode variable structure control and improved based on equivalent fixed-frequency simulation sliding mode control theory, the control system tuning parameters, and finally complete the simulation experiments verify the theoretical waveform.)

该程序是一个振荡相位噪声模型。相位噪声是衡量频率标准源(高稳晶振、原子频标等)频稳质量的重要指标，随着频标源性能的不断改善，相应噪声量值越来越小，因而对相位噪声谱的测量要求也越来越高。(The program is a model of phase noise oscillator. Phase noise is a measure of frequency standard source (high stability crystal oscillator, atomic frequency standard, etc.) an important indicator of the quality of the frequency stability, with the frequency standard source performance continues to improve, the corresponding noise value smaller, and thus the phase noise spectrum of the measurement requirements higher and higher.)

binary phase shift keying amplitude modulation

Modulation test for OFDM : This is a set of five (5) codes about COFDM (Coded Orthogonal Frequency Division Multiplexing) and coding schemes such as Convolutional, BCH, Reed Solomon (RS) and Low Density Parity Check (LDPC). The study uses an OFDM signal over an AWGN Channel with white Gaussian noise model, and calculate the Bit Error Rate wich is plotted.
