直接型到级联型的形式转换 ％ [b0,B,A]=dir2cas(b,a) ％b 为直接型的分子多项式系数 ％a 为直接型的分母多项式系数 ％b0为增益系数 ％B 为包含各bk的K乘3维实系数矩阵 ％A 为包含各ak的K乘3维实系数矩阵 ％(directly to the cascade-type conversion in the form of%% [belts, B, A] = dir2cas (b, a)% b-to direct the molecular polynomial coefficients% for a direct-denominator polynomial coefficients% of the gain coefficient belts% B To contain the bk K by the three-dimensional real coefficient matrix% A to include all ak K by the three-dimensional real coefficient matrix%)

调度模拟盘定义程序。可以定义开关旁路带的情况。(definition disk scheduling simulation procedures. Switching bypass can be defined with the situation.)

this code explains the performance of BPSK and QPSK modulation techniques in terms of there bit error probability. this code plots the simulated bit error rate of bpsk and qpsk in terms of SNR. both modulation techniques are explained in RAYLEIGH fading channel.

it has different programs they are useful

说明：  傅里叶变换能将满足一定条件的某个函数表示成三角函数（正弦和/或余弦函数）或者它们的积分的线性组合。利用傅里叶变换可对语音信号消噪。(ourier transform to meet certain conditions can be expressed as a function of trigonometric functions (sine and/or cosine functions), or their integral linear combination. Fourier transform to denoising the speech signal.)

Finite Volume Method 流体仿真代码 利用TDMA算法计算二维矩阵 从而计算出二位场内各点的性质 可以通过修改步长和网格大小实现算法研究(A computational fluid dynamics code for determine the property of a two-dimensional plate by using Finite Volume Method. Grid size and time step are free to change in this code.)

this is learning the code of pattern in matlab

变尺度随机共振代码，几年前用过的，喜欢的可以试试。(Stochastic resonance code, you can try a few years ago used.)
