直线阵自然指向性仿真,先根据设定的角频率仿真单频信号A sin(ωt);再根据阵元间距、入射角度计算得各阵元相对参考阵元接收的信号的时延 τ (dsin(θ))/c。
假设等间隔N基元线阵,入射信号是平面波,那么阵元输出信号为:S_n (t) A sin(ωt+nφ);其中 φ 2πfτ 为相邻阵元接收信号间的相位差;再将基阵各元输出求和,取最大值max,就得到输出幅度;以入射角为横坐标,幅度为纵坐标作图得直线阵自然指向性。

The demand of high data rate services has been increasing very rapidly and there
is no slowdown in sight. We know that the data transmission includes both wired
and wireless medium. Often, these services require very reliable data transmission
over very harsh environment. Most of these transmission systems experience much
degradation such as large attenuation, noise, multipath, interference, time variance,
nonlinearities and must meet the finite constraints like power limitation and cost
factor. One physical layer technique that has gained a lot of popularities due to
its robustness in dealing with these impairments is multi-carrier modulation technique.
In multi-carrier modulation, the most commonly used technique is Orthogonal
Frequency Division Multiplexing (OFDM)

dw to xls 这个是用于pb9下的,已经修改过,不会弹出demo。
pb8的。
pb8设置有点麻烦,因为pb9是可以直接把(dw to xls)
