this is the simulation of the relaying technique in all the channels using the amplify and forward and decode and forward protocols. it is also in the channels such as AWGN and also in the raileigh channels.the file also consists of the output graphs of all the simulations which are present in it.

说明：  通过状态空间方法建立了线性二自由度的车辆模型，然后通过转换，将状态空间转换成传递函数的形式，能看到速度变化后，质心侧偏角和横摆角速度的变化趋势。(The vehicle model with linear two degrees of freedom is established by the state space method, and then the state space is transformed into the form of transfer function through transformation. After the speed changes, the change trend of the sideslip angle and the yaw rate of the center of mass can be seen.)

In geometric camera calibration the intrinsic and extrinsic camera parameters are computed based on measured image coordinates of a know calibration target. These parameters may be used to correct distorted images or image coordinates(In geometric camera calibration the intrinsic and extrinsic camera parameters are computed based on measured image coordinates of a know calibration target.
