小数据量法计算 Lyapunov 指数的 Matlab 程序 - (mex 函数，超快)( Lyapunov number)

码分多址(CDMA)技术作为第三代移动通信系统的核心技术，具有容量大、抗干扰能力强等优点。然而,传统的CDMA系统属于窄带扩频系统,它的数据速率比较低,不能胜任新一代移动通信系统 （beyond 3G）高速数据通信的需要。而多载波传输技术－正交频分复用（OFDM），作为后三代移动通信的核心技术，则具有高数据速率传输的特点。(Code Division Multiple Access (CDMA) technology as the third generation mobile communication system' s core technology, high capacity, anti-interference ability and so on. However, the traditional narrow-band CDMA system is spread spectrum system, and its relatively low data rate, can not do next-generation mobile communication systems (beyond 3G) high speed data communication needs. The multi-carrier transmission technology- orthogonal frequency division multiplexing (OFDM), after three generations of mobile communications as a core technology, the high data rate transmission characteristics.)

采用eigen value来模拟各种衰落信道的源码程序，可以仿真瑞利衰落和AWGN叠加等等的情况。有详细注释。(Eigen value used to simulate a variety of fading channel the source program, you can simulation superimposed Rayleigh fading and AWGN and so on. Has detailed notes.)

In this simulink model , 16-QAM modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.

这是多相滤波器设计MATLAB仿真程序，献给大家做个参考(This is a polyphase filter design MATLAB simulation program, dedicated to be a reference to)

此程序用于在nw小世界网络中求特征根，通过输入节点总数，耦合数值和最大运行次数(This program is used to find the characteristic roots in nw small world networks, by the total number of input nodes, coupling values ​ ​ and the maximum number of runs)
