o here p q r s t of the electro cardia program is being explained

卡尔曼滤波的MATLAB实现，是一个教程事例(updates a system state vector estimate based upon an observation, using a discrete Kalman filter.)

this is programm for propagation that can help you to solve the case in propagation and transmission media fron transmitter to receiver. we can count link budget in propagation.
