基于细菌趋化的粒子群优化算法MATLAB源程序。(Bacterial chemotaxis based on particle swarm optimization MATLAB source code.)

该例程内容丰富，包括从基本的bpsk,qpsk,qam到实际的ofdm系统，cdma链路，mac层仿真分析，对OFDM信道建模，包括普通IDFT算法和IFFT快速算法，基于OFDM体制的调制和解调程序，降低OFDM系统PAPR的pts算法的仿真程序，完整的OFDM链路程序并作了较为具体的解析(The routines cover a wide range from basic bpsk, qpsk, qam to the actual ofdm systems, cdma link, mac layer simulation, the OFDM channel modeling, including ordinary IDFT algorithm and IFFT fast algorithm, based on OFDM modulation system and demodulation process, reduce the PAPR of OFDM system pts algorithm simulation program, a complete OFDM link process and made more specific analysis)

自己编写的短时傅里叶变换（STFT）程序，短时傅里叶变换可以获得非平稳信号的时频图，主要原理是用滑窗截取一段信号，认为这一段时间内信号是平稳的，对其进行fft变换获得频谱(I have written a short time Fourier transform (STFT) program, short-time Fourier transform can be obtained non-stationary signal frequency diagram, the main principle is the interception of a signal with a sliding window that within this period of time the signal is stationary, access to spectrum fft transform them)

说明：  1、主要是产生0，1，2，3，阶贝赛尔函数图形。 2、产生线性调频信号和它的的频谱图。 3、产生单个脉冲的三维模糊图以及对应的等值图。 4、它是程序3的嵌套子程序，用于产生单个脉冲。 5、用于产生高斯和瑞利分布函数。 (These programs can produce 1、Bessel graph；2、LFM signal and its amplitude spectrum；3、ambiguous graph 4、Gaussian and Rayleigh function. )

说明：  本函数将播放音乐《对面的女孩看过来》的前两句~(This function will play the music, &quot across from the girl,&quot the former two ~)

水和蒸汽性质计算V5.5，能够计算任何条件下水和蒸汽的参数，能够在matlab下使用。(Water and steam properties calculation V5.5, able to calculate any conditions of water and steam parameters can be used in matlab.)

利用tol和bol进行多基地的定位，最后给出GDOP图(TOL and BOL are used to locate for multi base, and finally the GDOP diagram is given)

ofdm系统当中的接纳控制技术 程序当中有三种接纳控制算法的对比 都是基于ofdm系统的 (ofdm systems Admission Control technology program has three admission control algorithms are based on the contrast o fdm System)

基于matlab的DTMF数字拨号音合成，通过的简单的时域连接，用于进一步分析合成效果。DTMF2是分析部分，用于显示时域波形，频谱图和语谱图。(Based on the synthesis matlab DTMF digit dialing tone, and connected by a simple time domain, for further analysis synthesis results. DTMF2 the analysis section, time-domain waveform, spectrum and spectrogram displays the)

说明：  电力系统拓扑分析、孤岛数，关联矩阵法把主接线的节点和母线的每一进出线连接点作为拓扑图的节 点，把开关元件作为拓扑图的支路，建立节点．支路关联矩阵表示电网的基本拓 扑结构。然后定义矩阵“与．或’’乘法运算，利用连通性的传递性质实现对电力 网络结构的辨识。(In the incidence matrix method, the node of the main connection and the connection point of each incoming and outgoing line of the bus are taken as the node of the topology diagram, and the switching element is taken as the branch of the topology diagram to establish the node.The branch correlation matrix represents the basic topology structure of the power grid)
