深度衰落 meaning in English

deep fading

However , high - speed data transmission system suffers from time - variant multi - path fading and inter - symbol interference ( isi ) . as a solution , adaptive equalization can effectively combat isi by compensationg for channel distortation
随着数据率的提高,信道呈现出频率选择性,信号的一些频率成分将产生深度衰落,产生码间干扰( isi ) ,影响系统的性能。
The simulation results show that our algorithm is effective in tracking the changing of channel without deep fading under the condition that transmission efficiency has been double compared with [ 113 ] with the same sub - carriers ; it is also effective to track the channel with deep fading under the condition that transmission efficiency has been increased obviously when linear precoded technology is used
仿真结果表明，当fir信道没有深度衰落时，本文的算法在相同的子载波和比[ 113 ]传输效率提高一倍的情况下，能有效地自动跟踪信道的变化；当信道有深度衰落时采用线性预编码的情况下，本文的算法在比[ 113 ]传输效率有较大提高的情况下，也能有效地跟踪信道的变化。
