摘要

本文提出了基于Fritchman分割有限状态模型(1967)的数字信道建模方法。在无误差运行分布(EFRD)的基础上确定过渡概率。对波特率为300bd的FSK信号和波特率为1600bd的8-PSK信号分别进行了误差序列的实验测定。实验在一个城市和一个农村地区进行。车速分别为40 km/h和100 km/h。着重分析了车速和信号方式对P(/spl ges/m,n)概率的影响。

Markov characterization of a digital channel

The paper presents the modeling of a digital channel on the basis of the Fritchman partitioned finite-state model (1967). The transition probabilities are determined on the basis of the error free run distribution (EFRD). The experimental determination of the error sequence is made for a FSK signal, with a baud rate of 300 Bd, and for an 8-PSK signal, 1600 Bd respectively. The experiment was performed in an urban and a rural area. The speed of the vehicle was 40 km/h, and 100 km/h respectively. The effects of the vehicle speed and signaling method upon the P(/spl ges/m,n) probability were emphasized for each case.
