Esprit-type algorithms for a received mixture of circular and strictly non-circular signals
2015 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
Recently, ESPRIT-based parameter estimation algorithms have been developed to exploit the structure of signals from strictly secondorder (SO) non-circular (NC) sources. They achieve a higher estimation accuracy and can resolve up to twice as many sources. However, these NC methods assume that all the received signals are strictly non-circular. In this paper, we present the C-NC Standard ESPRIT and the C-NC Unitary ESPRIT algorithms designed for the more practical scenario of a received mixturedoi:10.1109/icassp.2015.7178483 dblp:conf/icassp/SteinwandtRH15a fatcat:hhic7ctqbnghzmi36oy3ofafrm
