SHD-A model transmitter is applied to emit and convey baseband signal of sound, vibration and measure-control in aeronautical communication system from one point to mul-ti-point. SHD-A型多通道固态调频发射机系统主要应用于航空通信系统一点对多点的声音、振动、测控等基带信号的发射与传输.
To the numeri- cal results, one can see that the performance of the aeronautical communication system is worse than that for terrestrial cellular sys- tems and also depends logarithmically on both the cell radius and height. 从数据分析的结果可以看出航空通信系统的性能不如陆地蜂窝系统,并且与小区半径和高度成对数函数关系。
