Abstract :
This paper considers the problem of blind source separation of synchronous code division multiple access in non Gaussian channels. A novel algorithm based on variable step-size is proposed that improves the iterative M-estimator algorithm. Simulation results with comparing our newly modified algorithm with its previous counterparts are also illustrated.
