Abstract :
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(⩾m,n) probability were emphasized for each case
