Abstract :
A new constant modulus algorithm and two of its variants are presented for blind equalisation of complex-valued communication channels. The proposed algorithm is obtained by solving a novel deterministic optimisation criterion which comprises the dispersion minimisation of a priori as well as a posteriori quantities leading to an update equation having a particular zero-memory continuous nonlinearity. The convergence analysis of a variant of the proposed algorithm is presented.
