差分STBC仿真，包含2个发射机，1个接收机，使用psk调制(differential space time block code)

可以把一段脑电信号分解成多个频段，然后各频段重构就可以提取脑电信号的各频段成份了(Period of EEG can be broken down into multiple bands, each band then refactoring can extract EEG bands ingredients)

QPSK在加性高斯白噪声环境下，信噪比和误码率的仿真。 先产生一个四组符号的序列，再将该序列映射到对应的相位上。用相应的函数产生均值为零、方差为δ2的加性高斯噪声。 (QPSK the additive white Gaussian noise environment, and the signal-to-noise ratio of the simulation. First group have a four symbols of sequence, then this sequence mapped to the corresponding phase on. With the corresponding function have zero mean and variance of 未2 additive white Gaussian noise.)

dbf数据的读取，可用于高频数据处理，比如股票的分时、分笔、逐笔数据(read dbf data, can be used for high frequency data processing)

在盲辨识系统中，非常关键的是如何获得最好的辨识效果，这里采用了多种方法，通过系统建模，并比较方法(In blind identification system is critical to identify how to get the best effect, this uses a variety of ways, through system modeling, and comparison)

采用有限元法研究了圆形和椭圆形两种变形对称双脊波导对传输特性的影响。计算了脊的尺寸变化时的截止波长和单模 带宽，给出了主模场结构 图以及变形对截止 波长和单模带宽影响的关 系曲线 ，并分析 了传输特性 随对称脊波导结构尺寸变化的情况。通过这些研究，能够为变形双脊波导的应用和研究提供有价值的参考。 (Finite element method using the circular and elliptical symmetry Double Ridge Waveguide two deformation characteristics of the transmission. Dimensional changes were calculated when the ridge and single-mode cutoff wavelength bandwidth gives the dominant mode field pattern and deformation of single-mode cutoff wavelength and the bandwidth of the curve, and analyzed the transmission characteristics of ridge waveguide structure with symmetrical changes in size situation. These studies can be applied for the deformation Double Ridge Waveguide to provide a valuable reference and research.)
