Methods for Improving the Efficiency of Decameter Range Aviation Digital Radio 000_7.pdf

In aviation telecommunication, decameter range is widely used for solving different tasks associated with the objective functions of aircrafts during their interaction among themselves and with ground means. Considering the features of the specified wavelength range due to the wide development of digital data exchange methods, the challenge of achieving their credibility is arised. The solution can be found only in the way of conjunctive use of data protection tools.In the paper, the author describes the application of hierarchical modulation for transmission of error correcting code combinations processed with clustering on the receiver. It allows implementing the list decoding of received code vector with the use of the only one list, and, consequently, it simplifies the decoder. The method is effective only with correct recovery of cluster number. The cluster number bits are transmitted in hierarchical modulation with the use of the point of signal constellation remoted from each other in the most greatly manner. Also, the author estimates probabilistic system characteristics.

Signal-to-code design, hierarchical modulation, cluster, list decoding.
