Abstract :
New generation air traffic control requires the communication system to improve data rate and system capacity. Traditional TDMA and FDMA system can support limited users. Code Division Multiple Access (CDMA) may take advantages to provide better performance. Data rate and user capacity are two aspects of it. To a CDMA for air traffic control, Multiple Access Interference (MAI) and aircraft dynamics are the challenge. Matched filter based CDMA receiver must employ power control to overcome near-far effect, thus lowering MAI. High speed mobility makes the receiver design a tough issue. It can be seen from this work that adaptive receiver structure incorporating convolution code will suppress MAI in magnitude and change to airborne dynamics.
