Separation of Convolutive Mixtures of Linear Modulated Signals Using Constant Modulus Algorithm
Pierre Jallon, Antoine Chevreuil, Philippe Loubaton, Pascal Chevalier · 2006
The issue of separating linear mixtures of independent linearly modulated signals stemming from unknown digital communication systems is addressed. The baud-rates of the various transmitted signals are in particular unknown and possibly different. Therefore, sampled versions of the received signal are cyclostationary sequences. Despite the non-stationary environment of the data, Godard's algorithm is shown to achieve separation in rather general contexts.
