依据矩量法对偶极子天线和单线行波天线进行分析,将其分为多个小段,分别计算各段上的电流,然后根据电流分布计算出远场和近场的场强波瓣图,从近场随距离的明显变化得出天线近场分析的必要性。(Dipole antenna and a single-wire traveling wave antenna analysis based on the method of moments, will be divided into multiple small pieces, respectively, to calculate the current on each segment, the field strength of the far-field and near-field lobe diagram is then calculated according to the current distribution, draw antenna near-field analysis of the need for significant change with distance from the near-field.)

有约束最优化问题：利用matlab中已有的函数。举了一个利用里面函数求最小值的例子。这是最优化与运筹学中会经常遇到的问题(Constrained optimization problem: using the matlab existing function. For a use inside function minimise example. This was the optimized and operations research will often encounter problems )

The demand of high data rate services has been increasing very rapidly and there is no slowdown in sight. We know that the data transmission includes both wired and wireless medium. Often, these services require very reliable data transmission over very harsh environment. Most of these transmission systems experience much degradation such as large attenuation, noise, multipath, interference, time variance, nonlinearities and must meet the finite constraints like power limitation and cost factor. One physical layer technique that has gained a lot of popularities due to its robustness in dealing with these impairments is multi-carrier modulation technique. In multi-carrier modulation, the most commonly used technique is Orthogonal Frequency Division Multiplexing (OFDM)
