通常,对于相同调制方式的不同电台,用不同的载波频率来区分.但对于同一载波频率的不同电台,一般接收机就无法区分了.当两电台发射的同频信号到达接收点的电场强度相差较大时,接收机只能收到较强电场强度的电台,而弱电台信号被抑制了;当到达接收点的两个信号电场强度相近时,两信号在接收机中产生相互串扰而无法接收.本文介绍的方案是对载波 Normally, for different stations of the same modulation type, different carrier frequencies are used to distinguish them, but for different stations of the same carrier frequency, receivers can not be distinguished from each other. When the frequencies of the electric signals transmitted by the two stations at the receiving point differ from each other The larger the receiver can only receive the strong electric field strength of the station, and the weak station signal is suppressed; when the arrival of the receiving point of the two signal electric field strength similar to the two signals in the receiver cross-talk and can not receive The scheme introduced in this paper is for carrier
