Recognition of MQAM Signals in the Aeronautical Communication

Abstract:

For the complex recognition of signals in the aeronautical communication, the recognition of the star-type MQAM signals is studied under the aeronautical channel. The different scenarios of the aeronautical channel are analyzed and the reasonable channel model is established. The high order cumulant recognition algorithm which applies to the aeronautical channel is proposed, the invariant classification characteristics of modulation signals are constructed by this algorithm, and this algorithm is improved by using the receive diversity technique. Simulation results show that this algorithm significantly improves the correct recognition rate of the received signals has the good anti-fading and anti-noise performance and meets the requirements of the modulation recognition of MQAM signals under the aeronautical channel.
