％电影动画： ％1.首先调用moviein函数对内存初始化.创建一个足够大的矩阵来容纳一系列指定的图形（帧） ％2.调用getframe函数生成每一帧.该函数返回一个矢量，利用这个矢量创建一个电影动画矩阵 ％3.调用movie函数按照指定速度进行指定次数的播放 ％例子2：演示如何实现快速傅立叶变换（exp(j*2*pi/n)）的可视化过程( Movie animation: 1. First transfers the moviein function to the memory initialization Founds graph which an enough big matrix holds a series of assigns (frame) % 2. Transfers the getframe function to produce each This function returns to a vector, uses this vector to found a movie animation matrix % 3. Transfers the movie function according to assign the speed to carry on assigns the number of times the broadcast Example 2: How demonstrates realizes fast Fourier transforms (exp (j*2*pi/n)) the visible process )

小球的抛物线轨迹。将轨迹分解成x坐标和y坐标，计算出每一个时刻的x和y值，然后对x和y进行成像就可以得到轨迹了(Parabolic trajectory of the ball. The track is decomposed into x and y coordinates, x and y values calculated each time, then x and y can be imaged on a trajectory)

The channel estimation algorithm is based on a subspace approach. The method works only for identifiable STBCs (excluding >=1-rate STBCs). See publication [1] for more detail about the algorithm and the identifiability conditions. The zip file contains three m files. - space_time_coding.m (perform space time coding) - subspace_channel_estimation_STBC.m (channel estimation) - one_shot.m (show an example) To use these files, extract the three files in the same folder. Then, call the script one_shot in the matlab command window. Reference: [1] Ammar, N. Ding, Z.
