| الوصف: | 87 For data communications in CNS/ATM, the air-ground aeronautical telecommunication network requires irregular, high data rates of transmission in long bursts. The Aircraft Communication Addressing and Reporting System ( ACARS ) is a VHF radio currently used in air-ground Communications. Due to its low data transmission rate of 2.4 Kb/s, small communication capacity and high cost, ACARS can''t cope with the fast growing needs of high throughput in aeronautical communications. Because VHF Digital Link ( VDL ) can operate at a bit rate up to 31.5 Kb/s, and has larger capacity, it will gradually replace ACARS and become the key VHF data link system for the next generation air-ground data communications. The objective of the thesis is to develop the mode3 VDL prototype system which implements D8PSK baseband/IF band transceiver for physical layer protocols, and evaluate its performance over a Gaussian white noise channel when estimation errors of synchronization parameters including carrier frequency, phase and symbol timing exist. By the use of DSP on-line simulator ( LabVIEW ) and the associated wideband ADC/DAC module board, the VDL transceiver system is simulated, designed and tested ant its performance is assessed. The results from the thesis can facilitate the DSP chip-based design in the future for practical applications, and is anticipated to establish the key technology for the next generation air-ground communications. |
