Changes-in-the-signal-to-noise-ratio
等间距线性阵列,阵元数M=8,阵元间距d= λ /2,等幅加权,目标方位φr =0°。产生空间白噪声矢量(复高斯分布)。
设阵列信号矢量元素s(m)=exp[j mψr],其信号幅度为1,该阵元接收机附加的高斯噪声为n(m)=nmr+jnmi,其中实虚部均为独立同分布N(0, σ2)的高斯随机数,则该通道合成信号x(m)=s(m) + n(m),其中信噪比为:
SNR = 10 lg[1/(2σ2)] = – 3 – 10 lg(σ2) (dB)
(The spacing of the linear array, and the array element number M = 8, the array element spacing d = λ/2, equal amplitude weighted target azimuth φR = 0. Space generated white noise vector (complex Gaussian distribution). Let array signal vector elements s (m) = exp [j mψr], the signal amplitude, the element receiver additional Gaussian noise n (m) = nmr+jnmi which the real and imaginary parts are independent and identically distributed N ( Gaussian random numbers of 0, σ2), the channel the synthesis signal x (m) = s (m) the PPLS n (m), where SNR is: SNR = 10 lg [1/(2σ2)] =- 3- 10 lg (σ2) (dB))

BP神经网络预测公路运量
1.问题的描述
公路运量主要包括公路的客运量和公路货运量两个方面。据研究,某地区的公路运量主要与该地区的人数、机动车数量和公路面积有关,表1给出了20年得公路运量相关数据,表中人数和公路客运量的单位为万人,机动车数量单位为万两,公路面积的单位为万平方千米,公路货运量单位为万吨。
根据有关部门数据,该地区2010年和2011年的人数分别为73.39和75.55万人,机动车数量分别为3.9635和4.0975万辆,公路面积将分别为0.9880和1.0268万平方米。请利用BP神经网络预测该地区2010年2011年得公路客运量和公路货运量。

FUZZY_ACDCSYSTEMS
This paper discusses the impact of HVDC on
Power System Stability and proposes a new control mechanism
based on Fuzzy set theory to augment dynamic performance of
a multi-machine power system. To have good damping
characteristics over a wide range of operating conditions,
deviations in speed and acceleration of the machines are chosen
as the input signals to the fuzzy controller. These input signals
are first characterized by a set of linguistic variables using fuzzy
set notations .The fuzzy relation matrix allows a set of fuzzy
logic operations that are performed on controller inputs to
obtain the desired output. The effectiveness of the proposed
controller is demonstrated by a multi-machine system example.
The performance of this fuzzy controller, in comparison to the
conventional fixed gain controller, demonstrates the efficacy of
this new fuzzy PID controller.
