代码说明:

  使用鏡子鏡射的原理,也就是將接收點鏡射之後,求取傳送點與接收點的距 離,而因為公式(1)及公式(8),可知角度與距離有關係,可以使用這個公式來直 接代入公式(10)之中。(. The receiver is located at the center of a 50-m*50-m room and transmitter is moved along a straight from 2m to 20m from the receiver. Show the received power in decibels versus distance for the LOS path, and include all the first-, second-,third-order reflections. (Gt = Gr = 1.6, f = 1GHz, a =-0.7, Pt = 1W))
