关于db4小波数据处理的一个简单matlab程序，可供大家参考参考(simple matlab test of xiaobo,it is expected hopleful)

说明：  Nakagami-m分布能用来对比瑞利分布条件更苛刻的衰落信道进行建模，最适合于郊区无线多径信道上接受的数据信号，瑞利分布是它 时的特例。(Nakagami-m distribution can be used to model fading channels with more stringent Rayleigh distribution conditions. It is most suitable for data signals received on suburban wireless multipath channels. Rayleigh distribution is its special case.)

The Robotics Toolbox provides many functions that are useful in robotics such as kinematics, dynamics, and trajectory generation. The Toolbox is useful for simulation as well as analyzing results from experiments with real robots.

This code has been used and seems to be free of error. However, it carries no explicit or implicit guarantee.
