基于Watterson模型的短波信道马氏性研究
Research on Markov Characteristics for High Frequency Channel Based on Watterson Model
摘要
Abstract
A study of Markov characteristics for simplifying the model of high frequency channel is presented aiming at the problem of the randomly time-varying tap which is difficult to estimate. By partitioning the continuous-value channel gain into a finite number of states are modeled as a first-order Finite-state Markov(FSM) chain. The parameters of the FSM model such as stationary probability and transition probability are calculated with the given fading characteristic parameters. It analyzes the average error probability and the characteristics of state duration for the FSM model. The validity and accuracy of the model are confirmed by the simulation.关键词
