A Blind Signal Extraction Algorithm Based on Cyclostationary Constraint
Yiyu Zhou · Journal of Astronautics · 2012
Signals of interest(SOIs) extraction is a vital issue in the field of communication signal processing.In this paper,the cyclostationary property of communication signals is incorporated into the constrained ICA(cICA) framework to form a new constrained optimization problem.The approach incorporates cyclostationarity constraints in the ICA process to perform separation and selection of the SOIs simultaneously.Numerical simulations demonstrate the effectiveness and higher performance of the proposed algorithm compared with the conventional ICA algorithms such as FastICA.
