移动通讯系统的性能首要遭到无线信道的制约。无线信道不像有线信道那样固定并可预见,而是具有极度的随机性,从简单的视距传达,到遭受各种凌乱的地势、地物,乃至移动台的速度也会对信号电平的式微产生影响。因而,要对无线信道进行控制和猜想是非常困难的。

(The performance of the mobile communication system is primarily restricted by the wireless channel. Wireless channels are not as fixed and predictable as wired channels, but are extremely random, ranging from simple line-of-sight communication to being subjected to various cluttered terrain, features, and even the speed of mobile stations. The decline has an impact. Therefore, it is very difficult to control and guess the wireless channel.)
