用matlab7.0软件对通信信号进行调制数字通信系统通信系统调制解调(PL_FSK)VHDL建模,包括发送和接受模块PL_FSK(good)

小生境遗传算法用于优化问题，得到了比遗传算法更好的效果(Niche genetic algorithm for optimization problems, get better results than the genetic algorithm)

The program implements the use of χ2 test for determining the distribution law of fluctuations of the signals. Hypotheses about the distribution of this or innogo parameter system, such as expectation, variance, probability density for a given level of significance accepted or refuted, in accordance with the results. The program implements two distributions: the exponential and Rayleigh.

CDMA的MATLAB仿真，可以进行不同信噪比下的误码率分析。(MATLAB simulation of CDMA can be carried out under different signal to noise ratio of the bit error rate analysis.)

OFDM通信系统发射机和接收机的CIC滤波器设计(OFDM communication system transmitter and receiver filter design CIC)

这是进行matlab的fft频响函数估计，它可以进行随机激励的频响估计(this is a program which is fft analysis it can uate frf that is random exict)

遗传算法进可攻倘若覆盖就换个家看看回归那个符号那风格(Progressive genetic algorithm could be another attack if the coverage on the house to see)

实现信道的交织解码和解交织解码，用于OFDM通讯系统中(Achieving channel interleaving decoding decoding deinterleave)

复合材料的优化,内容里边有很好的描述以及很多的计算实例,适合进阶学习(Objective of this Matlab s program was researched optimization analysis of laminated composite plates for determined the ultimate strength and stress effects of plate s under the regular and uniform out-loads. Therefore, generally Reissner s flat and thick shell finite element model (4Node-20Dof) was developed with first-order shear deformation theory (FSDT). Kirchhoff s classical laminate plate theory yields in adequate results for thick plates (a/th<20). This classical laminated plate (CLPT or CPT), was one of the first developed by Reissner with shear deformation theory. Afterwards, Mindlin was utulizated this shear deformation theory to accommodate rotary of inertia terms on per unit freedom. If this plate system s be very thick (a/th<10) than it is fail to shear deformation-motion and it s condition of adaptive shear stress on plate s top and bottom surface. While this conditions was produced on plate s segment when requered the shear correction factor of shear locking eff)
