| Summary: | Providing broadband communication service in High Altitude Platform Station
(HAPS) is a new idea that proper to be discussed. One of this services is adopting
OFDM transmission technique as digital modulation medium applicable in HAPS.
HAPS technology is an alternative that can be covered the lack of terrestrial and
satellite technologies.
In this final project, writer studies about the performance of OFDM system in
HAPS channel, where it has known as Rician fading channel. In real condition, received
power in HAPS channel is composite of dominant / LOS signal power and multipath
signal power. The parameter that describe comparison of dominant signal power and
multipath signal power is K factor. Elevation angle increase between HAPS platform
and terminal user cause K factor value raising and affect the performance of OFDM in
multipath fading condition.
The result shows the increase of elevation of angle (in this case K factor is also
increasing) makes system performance works better. However OFDM system
performance is getting worse when bitrate and Doppler spread increased. |
