On Improvements of Cyclic MUSIC
EURASIP Journal on Advances in Signal Processing, 2005 Many man-made signals encountered in communications exhibit cyclostationarity. By exploiting cyclostationarity, cyclic MUSIC has been shown to be able to separate signals with different cycle frequencies, thus, to be able to perform signal selective ...
