In this paper, the ground-to-air channel model is studied and the simulation results of the model are provided. Then, we implement it in the improved single carrier frequency domain equalization (SC-FDE) system and compare the transmission characteristics in different conditions. Theoretical analysis and simulation results show that the BER performance of the proposed system can reach 10-7 or even...
OFDM can maintain good performance even in frequency selective fading environments, but the transmission characteristics of high-speed mobile communication systems are considerably degraded due to the channel time-variation caused by the Doppler effect. Lowering the velocity of the receiving antenna relative to the ground reduces this degradation. In this paper, in order to lower the speed of the...
5 Gbit/s modulated optical solitons were transmitted through a 3000 km optical fibre with 91 Er-doped fibre amplifiers. No error floor below 10/sup -10/ BER was observed and the measured power penalty at 10/sup -9/ BER was 1.4 dB. The effect of fibre chromatic dispersion on the transmission characteristics was also investigated.<<ETX>>
