Response of ergodic system caused by chaos or noise input 混沌性或噪声信号引起的确定性响应
Noise inputs that enter the system with the command input require filtering techniques to remove or suppress them without affecting the command input itself 随着命令输入进入系统的噪声输入需要滤波器进行驱除或者抑制并不对输入信号产生影响。
This approach only requires the noise inputs to be energy - bounded instead of gauss white noises . the main results can be expressed by lmi after some matrix manipulations 该方法不需要限定系统的噪声输入信号为高斯白噪声,而只要求噪声信号为能量有界。
Abstract : a noise model for the analog correlator used in the ultra wideband receivers is proposed due to lack of simulation capability on noise performance of the correlator in current eda tools . the analog correlator circuit is divided into several parts to calculate the equivalent noise sources respectively . the ideal impulse generators , instead of the noise sources , are then applied to obtain the time varying transfer functions . fourier transforms are carried out to explore the relationship between the noise input and output in frequency domain for each part . then the symmetrical noise sources are grouped together and the periodicity of the circuit is utilized to further simplify the model . this model can be used to evaluate noise performance of the correlator 文摘:给出了分析模拟相关器的噪声模型.将相关器分成不同的几个子模块后,对各模块分别计算等效噪声源.然后用理想脉冲源代替噪声源计算电路的时变传输函数,接着用傅里叶变换计算输入输出的频域关系.利用电路的对称结构合并对称的子模块可以进一步简化模型.该模型可以用来估计相关器的噪声性能
