％ OFDM系统的发送，通过多径衰落信道，接收，判决 ％ 信道使用jakes模型。 ％ 时间色散系数我使用[0.9, 0.8 , ....., ]，你们自己去修改。 ( OFDM system to send, through the multipath fading channel, receive, sentence channel using Jakes model. Dispersion coefficient of the time I used [0.9, 0.8, .....,], to amend your own.)

matlab程序运行时导入数据文件作为输入参数，wolf 方法计算李雅普诺夫指数,基于混沌的模拟退火算法。( Import data files as input parameters matlab program is running, wolf calculated Lyapunov exponent, Chaos-based simulated annealing algorithm.)

A matrix of symbolic elements is reasonably useful for many analytic linear algebra applications, and for analytic vector, matrix and tensor differentiation. This function produces a matrix of arbitrary dimension of symbolic elements that are indexed by their position in the symbolic matrix for ease of reference. EXAMPLE >> M = symMat([2 2], m , real ) M = [ m11, m12] [ m21, m22] >> class(M) ans = sym >> det(M) ans = m11*m22 - m12*m21
