The principle of space time block coding with 2 transmit antenna and one receive antenna is explained in the post on Alamouti STBC. With two receive antenna’s the system can be modeled as shown in the figure below

Run the program by typing DoublePendulumAnimation at the Matlab prompt. Make sure that your current directory in Matlab is set to the directory containing DoublePendulumAnimation.m. To run the animation with the default parameters, simply click the Begin button to start the animation. You can experiment by changing the parameters and initial conditions and hitting the Begin button to see the motion of the double pendulum. 1)If the animation goes too slowly decrease the number of points. 2)If the animation is too fast or jerky increase the number of points. 3)Vary the time span to either increase or decrease the length of the animation.
