代码说明：

在移动数据通信系统信号经传播媒介到达接收端会发生畸变，现行的通信系统普遍采用自适应均衡技术来克服ISI和多普勒扩展。自适应均衡技术需要重复发送已知的训练序列直至有效均衡为止I。“盲均衡(Blind Equalization，BE)111”技术仅利用接收序列本身的相关性便可均衡信道特性。(Signal in the mobile data communication systems to reach the receiver via the mass media distortion occurs, the existing communication systems are generally adaptive equalization to overcome ISI and Doppler spread. Adaptive equalization techniques need to send a known training sequence repeated until an effective balance date I. " Blind equalization (Blind Equalization, BE) 111" technology is only used to receive serial correlation in itself can be balanced channel characteristics.)

This paper presents a new and efficient approach for capacitor placement in radial distribution systems (RDS) that determine the optimal locations and size of capacitor with an objective of improving the voltage profile and reduction of power loss. The solution methodology has two parts: in part one the loss sensitivity factors (LSF) are used to select the candidate locations for the capacitor placement and in part two a new algorithm that employs Dijkstra Algorithm (DA) is used to estimate the optimal size of capacitors at the optimal buses determined in part one. The main advantage of the proposed method is that it does not require any external control parameters. The other advantage is that it handles the objective function and the constraints separately. The proposed method is applied to 33 & 69 RDS. The solutions obtained by the proposed method are compared with other methods. The proposed method has outperformed the other methods in terms of the quality of solution. OPTIMAL C
