说明：  在三维空间中画泡泡,可以指定在三维空间中的x,y,z的坐标以及泡泡的半径r和颜色c(RGB).(BUBBLEPLOT3(x,y,z,r), where x, y, z and r are four vectors of the same length, plots bubbles of radii r in 3-space with centers at the points whose coordinates are the elements of x, y and z. If r is a matrix of size numel(x)x3, BUBBLEPLOT3 produces ellipsoids with centers x(i),y(i),z(i) and radii r(i,1), r(i,2) and r(i,3). BUBBLEPLOT3(x,y,z,r,c), where c is a rgb-triplet array (in [0,1]) with numel(x) rows, plots bubbles with colours specified by c. )

function [a,b] = pade(x,p,q) PADE Model a signal using the Pade approximation method ---- Usage: [a,b] = pade(x,p,q) The input sequence x is modeled as the unit sample response of a filter having a system function of the form H(z) = B(z)/A(z) The polynomials B(z) and A(z) are formed from the vectors b=[b(0), b(1), ... b(q)] a=[1 , a(1), ... a(p)] The input q defines the number of zeros in the model and p defines the number of poles.

利用列维（levy）法进行系统辨识，主要用于参数辨识(The use of Levy (levy) system identification method, mainly used for parameter identification)

通过计算和作图，比较4PSK和QPSK这两种不同的编码方式之间的优略，说明发射信号一个是三值的一个是二值的(By calculating and plotting, preferably QPSK, and compare these two 4PSK encoding between different strategies, a description of the transmission signal is a ternary value is two)
