Preliminary Result of Ionospheric Channel Characteristic Observation Over Java Island, Indonesia

Ionosphere channel characteristic is needed for designing a digital ionosphere communication system. Although International Telecommunication Union (ITU) already provide the general classification of earth ionosphere channel characteristic in three different conditions and three different regions, the empirical data are still needed in order to verify and enrich the information of channel characteristic for real implementation purposes. One of the methods that use to obtain the channel characteristic is the channel impulse response (CIR) observation. In this paper, the preliminary results of ionosphere channel characteristic observation over Java island Indonesia using CIR method are reported. As part of low latitude and Equatorial Ionosphere Anomaly (EIA) region, the Power Delay Profile (PDP) and root mean square (r.m.s) of time delay from the channel characteristic observation are given. That information is potential to be used in the design of digital ionosphere communication system.
