The results indicate : ( 1 ) there are interactions between the neurons in iso - frequency laminas and hetero - frequency laminas , and the mutual inhibition is predominant ; ( 2 ) the mutual inhibition of the inferior collicular neurons can increase the frequency selectivity , and play an important role in modifying the discharge features of the neurons 上述结果表明: ( )下丘神经元声信号处理过程中,位于同频层内及非同频层的神经元之间存在相互作用,该作用以相对抑制为主; ( 2 ) ic神经元之间的相互抑制作用可增强神经元的频率选择性,并对神经元的发放特征有重要的修饰作用。
Be based upon the studies of sea optical scatter channel by use of monte carlo simulation , the channel is described as a multipath routeway in this paper . the effect on the communications performance , created by the frequency selectivity decline caused by the multipath routeway , is worked over . the correlation bandwith of sea optical scatter channel is analyzed and quantified through the simulation on the computer 基于对海水信道的蒙特卡罗模拟,本文对海水信道进行了多径化描述,研究了由于信道的多径化所产生的频率选择性衰落对通信质量的影响,分析并通过计算机模拟确定了海水信道的相关带宽。
