实现粒子群算法的PID控制功能，针对具体算例得出运行结果(Particle swarm optimization to achieve PID control functions, specific examples drawn operating results)

FDTD仿真喇叭天线，能观察得到其电场在自由空间随时间的分布情况。(FDTD method is a time domain analysis.Here we first we design a wave-guide and there after we just increase its broad side.Our aim is to this simulation is plotting its electric field response with time and how will it response in outside free space. Here we just take 170 time steps one who can interested in antenna designing they can also plot the radiation pattern of this HORN antenna.Just take the field in the outside the mouth of HORN antenna and there do the simple formula to near filed far field transfer and measure it at your band of antenna.Best of LUCK all of you.)

Code division multiple access (CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, which is where several transmitters can send information simultaneously over a single communication channel. This allows several users to share a band of frequencies (see bandwidth). To permit this to be achieved without undue interference between the users CDMA employs spread-spectrum technology and a special coding scheme (where each transmitter is assigned a code). Each user in a CDMA system uses a different code to modulate their signal. Choosing the codes used to modulate the signal is very important in the performance of CDMA systems. The best performance will occur when there is good separation between the signal of a desired user and the signals of other users.

matlab program numerical methods

这个matlab程序主要介绍的而是OFDM调制过程，主要设置了符号数，载波数，循环前缀大小，对信号进行了IFFT变换，串并转换等。(The matlab program introduces the OFDM modulation process but the main set of symbols, the number of carriers, cyclic prefix size, the signal of the IFFT transform, string and conversion)
