一、 本程序采用16QAM调制方式,对一串2进制信源进行调制,用升余弦滚降函数进行基带调制,再调到高频信道;在信道上加入高斯白噪声,运用匹配滤波器解调,画出解调星座图,运用最小欧氏距离译码判决,计算误比特率。(First, this program uses 16QAM modulation mode, for a string of two binary source is modulated with a raised cosine roll-off function for base-band modulation, and then transferred to high-frequency channel in the channel by adding Gaussian white noise, the use of matched filter device demodulator, draw demodulation constellation, using the minimum Euclidean distance decoding decision, calculate bit error rate.)

小波包变换可以对高频部分提供更精细的分解,而且这种分解既无冗余,也无疏漏,所以对包含大量中、高频信息的信号能够进行更好的时频局部化分析。(Wavelet packet transform can provide the high frequency part of the finer decomposition, and this decomposition is neither redundant nor oversight, so the signal contains a large amount of high frequency information can be a better time-frequency localization analysis.)

swept-sine-vibration
基于ANSYS APDL二次开发的航电设备的动力学扫频分析,载荷输入条件为交越频率以下为恒定位移,交越频率以上为恒定加速度。我将加速度输入转换为位移输入,将位移和加速度两段输入载荷统一按照位移载荷输入,将位移存入表数组,利用ANSYS APDL自动将扫频范围内的位移载荷存入表数组,并循环加载计算,实现了该工程结构的正弦扫频振动分析。(Kinetic sweep analysis, load input conditions of secondary development based on ANSYS APDL avionics for the crossover frequency less constant displacement, above the crossover frequency is constant acceleration. I will convert the input displacement input acceleration, displacement and acceleration loads unity in accordance with the displacement of the two input load input, the displacement of the array into the table using ANSYS APDL automatically load displacement within the sweep range of the array into the table, and cyclic loading calculated to achieve a swept sine vibration of the project structure.)
