Abstract :
A recent development in the literature has proposed a cosine modulated filter bank-based multicarrier modulation technique with blind equalization capability. However, convergence studies of the proposed blind equalizer have been carried out through computer simulations only. We present a thorough study of the blind equalizer by analyzing its associated cost function and show that it has two global minima and two saddle points.
