Performance study of channel estimation for DVB-T services in HAPS communication

DVB-T (Digital Video Broadcasting-Terrestrial) is an open standard in digital video transmission which has been internationally recognized. DVB-T standard issued by ETSI. This research will analyze the effect of DVB-T channel estimation for coverage improvement on High Altitude Platforms Station (HAPS)system. HAPS are known as stratospheric broadband telecommunications infrastructure is a standard similar to the satellite, which was placed in the stratosphere. HAPs channel can provide LOS relationship between HAPS platform with the user so that it can be simulated with rician channel. Based on the research results, the performance of DVB-T services in the HAPS system is influenced by the type of modulation used and the mode of work, the influence of channel estimation using least squares (LS) to increase coverage up to 34.4 km with a value of Eb/No 20 dB.
