本程序研究了已知电位分布的带电导体棒和方形平板的电荷分布模型，并利用矩量法对导体棒电荷线密度和平板的对角线电荷密度进行求解。讨论了不同模型下的算法和划分格数对电荷线密度结果的影响并经行了对比分析。(This program studies the charge distribution model charged conductor rods and square plates known potential distribution, and use of the method of moments for the diagonal line charge density charge density conductor rod and plate solve. The effects of the algorithm and divide the number of cells under different models of the charge line density results and comparative analysis by the line.)

将用matlab编译的N－R法用于潮流计算是以导纳矩阵为基础的，由于利用了导纳矩阵的对称性、稀疏性及节点编号顺序优化等技巧，使N－R法在收敛性、占用内存、计算速度方面的优点都超过了阻抗法，成为六十年代末期以后普遍采用的方法。(Matlab compiler will use the N-R method for power flow calculation is based on admittance matrix-based, due to the use of the admittance matrix of the symmetry, sparsity and node ID, such as sequential optimization techniques, so that N-R method in convergence , memory, computing speed advantages over the impedance method, the late sixties to become widely used method.)

In Modulation schemes such as OFDM transmitter time domain signal will have higher PAPR, which leads to various distortions in the transmitter chain and degradation of system performance i.e. BER/PER. Also requires highly linear power amplifier which increases cost of the system. PAPR is ratio of peak power to average power of time domain complex baseband signal which is to be transmitted. We will discuss PAPR reduction techniques below.
