RECEPTION RANGE ANALYSIS OF AN AIS SDR RECEIVER
Matej Bažec, Franc Dimc, University of Ljubljana, Faculty of Maritime Studies and Transport, SLO
A new, entirely software-based AIS SDR receiver has been written in C. Such an approach allows a low-budget AIS receiver or a network of such receivers. In the beginning, a basic description of concepts is presented, such as effective triggering in order to minimize computational power. Then, the efficiency of such a receiver is analyzed. The study is performed from the point of view of adequate signal reception in various conditions, such as increasing distance and geographical obstacles.
