Channel Estimation Scheme for the Enhanced Reliability in the Flying Ad-hoc Network
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 4
Abstract
This paper proposes the improved channel estimation for flying ad-hoc network (FANET). The FANET means the wireless communication network between the unmanned aerial vehicle (UAV). UAVs have unlimited availability not only in war but in various fields such as reconnaissance, observation, exploration. Due to the high-mobility of the UAVs, these channels of the FANET environment are very dynamic and time varying channel. Because the FANET for UAV transfers data such as the information on mission accomplishment, collision prevention, etc., the FANET requires the robust and spectral efficient communication scheme in the fading channel. IEEE 802.11p is considered as a communication method between UAVs. However, IEEE 802.11p suffers from the challenge of robust channel estimation due to rapid time-varying nature of the channel. In the IEEE 802.11p, the long training symbols are used for fine synchronization and channel estimation. This channel estimation scheme isn’t suitable in the time varying channel. This paper proposes the scheme that uses the pilot symbols and recovered symbols to estimate channel. The proposed scheme can provide the reliable wireless communication for the FANET.
