Mohamed Ismail Ibrahim, Abdelhamid Gaafar, Khairy A. Elbarbary . Improvement the Performance of Helicopter Satellite Communication using 2x2 Alamouti Scheme. International Journal of Computer Applications. 87, 8 ( February 2014), 6-10. DOI=10.5120/15226-3741
In helicopter satellite communications, the periodic blockage of the received signal and the carrier frequency ?uctuation are the most important problems. This paper proposes a space signal processing with time diversity combining scheme for helicopter satellite communications. In the proposed scheme, a space signal processing combining with time diversity tracks the carrier frequency ?uctuations due to Doppler shift . Results of computer simulation show that the proposed scheme improves the BER performance of the previous conventional scheme.
