Abstract
A new quasi-Newton multi-user constant modulus algorithm (QN-MUCMA) for mitigation of intersymbol interference (ISI) and cochannel interference (CCI) in multi-user communications is introduced. Compared with the conventional constant modulus algorithm with decorrelation cost, the proposed algorithm achieves fast convergence by the exploitation of Hessian information within the weight update equation. Simulations support the improved convergence properties of the algorithm
