多径衰减 meaning in Chinese

multipath fading

First of all , the characteristics of different adaptive algorithms and equalizers are theoretically researched . then digital microwave communication system model is build by simulink . based on this model , the convergent behavior and bit error rate performance of three equalizers ( nlms , kalman and rls ) are compared in multi - path fading channel
为了达到这个目的,首先需要从理论上对各种自适应均衡算法以及自适应均衡器的特性进行深入研究;然后利用simulink建立接近实际环境的数字微波通信系统,在多径衰减信道环境下比较了三种基带均衡器( nlms , kalman和rls )的收敛特性以及系统误码特性,并比较了nlms基带均衡器和通带均衡器的性能。
