Abstract This paper studies the steady-state of a robust cascade constant modulus(CM) array in alpha-stable distribution noise environment. A new signal canceller is proposed to cancel the captured signal by the previous beamformer. The convergence behavior of the canceller weight vector is examined. The behaviors of signals and alpha-stable noise transmitting along the cascade CM array are investigated. Computer simulations are presented to support this theoretical analysis.

Key words： Constant modulus array Beamformer Signal canceller Cochannel signal copy;Alpha-stable distribution Fractional lower-order statistics theory
