| Popis: | We sketch the components of a system designed to compete in the Battle of the ModRecs Workshop at DySPAN 2017. The core ideas are the use of a flexible channelized receiver for obtaining the complex envelopes of variable-bandwidth bands-of-interest and the use of the spectral correlation function (SCF) and higher-order cyclic temporal cumulants (CCs) for blind modulation recognition and parameter estimation. The use of CC features is greatly enhanced by the addition of a unsupervised clustering algorithm for constellation-size estimation. |
