A moving window algorithm for l∞ norm based blind source separation approach

An l_∞ norm based Source Separation Method has recently been introduced [1, 2], with the corresponding subgradient based algorithm that has a simple update rule. In this article, we propose a moving window modification to this algorithm, where instead of a long fixed window, a shorter length moving window is used. The simulation results for different blind source separation setups suggest that a significant level of complexity reduction can be achieved via use of the proposed approach.
