信道间干扰 meaning in English

ici inter-channel interference
interchannel interference

A group of orthogonal frequency carriers are used in ofdm system to improve the using rate of spectrum . if the orthogonal character can be held and ignore the inter - channel interference ( ici ) , the symbol error character of ofdm depend on the modulate of source codes . this dissertation propose the theoretic formula of ofdm - qam and ofdm - psk in this precondition
为了提高频谱利用率, ofdm系统使用了一组正交的子载波来传输信号,若能保证各子载波间的正交性不被破坏、不考虑信道间干扰( ici ) ,则ofdm系统的误码性能由信元调制方案的误码性能决定,文中推导了该情况下ofdm - qam和ofdm - psk的理论误码率公式。
