EFFECTS OF MULTIPATH PROPAGATION CHANNEL IN TIGRIS RIVER by Murad Shahadha Mahmood, Yasin Yousif Al-Aboosi

“…The distance from the sender to the receiver are (100m, 1000 m, and 5000m). With the use Ray model, results have shown that the multi-path propagations dominate in a case where the distance from sender to receiver, has been increased, which resulted in decreasing the grazing angle, thereby, increasing the coefficient of reflection. …”
