这是使用射线跟踪法求解墙体造成误差的程序，分别有穿单面墙，平行双墙，垂直双墙的情况(This is to use ray-tracing procedure for solving the error caused by the wall, respectively, through a single wall, parallel to the double wall, vertical double-wall case)

说明：  一个产生RS伪随机码的system generator 的建模，兄弟自己编的哦，绝对原创(RS produced a pseudo-random code system generator modeling, compiled by his brother, Oh, absolutely original)

As shown in (5), the inductor current oscillates around a dc value at twice the grid frequency. The PWM technique assumes a constant dc input current and thus,
