Abstract :
The aim of this letter is twofold: 1) to stabilize a fast adaptive noise subspace algorithm, which was proposed earlier in the literature under the name of FRANS algorithm and 2) to present a low computational cost version that is free from any square root and division operations, which is very suitable for VLSI implementation. A stability analysis and simulation results are also given in order to assess the performance of this algorithm.
