N2 - The adaptive equalization technique is an effective approach to eliminate the inter-symbol interference (ISI). It is known that the RLS algorithm has been widely used to update the tap weights of equalizers in most cases. However, it is restricted to being implemented on hardware platforms because of its large computational complexity. Considering this, we have proposed an improved algorithm combined with the coordinate descent method in this paper. The simulation results confirm that the novel algorithm achieves faster convergence rate and lower steady-state errors than the traditional RLS algorithm.
