Abstract :
Geometrically speaking, ICA (independent component analysis) estimation can be completed through angle transformation. Hence, the paper presents a novel lattice ICA estimation algorithm based on schur-lattices. In contrast to other algorithms, a lattice algorithm is more stable and convenient to be extended and implemented. Simulation results show satisfactory performance.
