Abstract :
Using a lattice in a two windowed multimodulus algorithm (WMMA), i.e. half constellation WMMA and edge-point WMMA, are considered. In comparison to MMA, WMMA is mostly utilized to decrease the cost function values when the number of symbol levels increases. Lattice, as a known whitening filter, causes the rate of convergence to be improved in blind equalization. Simulation results present the effectivity of the lattices in two WMMAs.
