CAPONWAVE
波束形成就是从传感器阵列重构源信号。(1)、通过增加期望信源的贡献来实现;(2)、通过抑制掉干扰源来实现。经典的波束形成需要观测方向(期望信源的方向)的知识。盲波束形成试图在没有期望信源方向信息的情况下进行信源的恢复。
波束形成技术的基本思想是:通过将各阵元输出进行加权求和,在一时间内将天线阵列波束“导向”到一个方向上,对期望信号得到最大输出功率的导向位置即给出DOA估计。
虽然阵列天线的方向图是全方向的,但阵列的输出经过加权求和后,却可以被调整到阵列接收的方向增益聚集在一个方向上,相当于形成了一个”波束”。这就是波束形成的物理意义所在。

short-termloadforecastingwithchaostimeseries
文章展示了一种新的方法用于功率系统中短期负载预测。提出的方案使用混沌时间序列分析基于确定性混沌去捕捉复杂的负载行为特征。确定性的混沌允许我们重构一个时间序列并决定输入的变量个数。这篇文章描述了混沌时间序列对日间功率系统峰值的分析。确定性混沌的非线性图形通过多层感知器的神经网络得到。提出的方案在一个例子中具体阐述。(This paper presents a new approach to short-term load forecasting in power systems. The proposed method makes use of chaos time series analysis that is based on deterministic chaos to capture characteristics of complicated load behavior. Deterministic chaos allows us to reconstruct a time series and determine the number of input variables. This paper describes chaos time series analysis of daily power system peak loads. The nonlinear
mapping of deterministic chaos is identified by the multilayer perceptron of an artificial neural network. The proposed approach is demonstrated in an example.)

simulace
his master’s thesis deals with satellite transponders. Firstly, satellite communication basics, satellite services definitions, frequency bands and satellite orbits are investigated. The second chapter forms the satellite transponders analysis. The transparent transponder and the transponder with on-board processing are described. Finally, a transponder model is designed and simulated in communication chain.
