Abstract. In this paper, we derive a new normalisation technique for Frequency Domain Adaptive Filtering (FDAF) algorithms. FDAF algorithms are well-known for their low computational complexity and for their decorrelating property that allows the use of different step sizes for each adaptive weight, yielding a uniform convergence of all the modes of the input signal. In these algorithms, normalisation is done by recursively estimating the power of each frequency bin. By introducing a normalisation based on an orthogonal projection (as is the case for the Affine Projection algorithm), we derive new frequency domain adaptive ltering algorithms and show by means of simulation that the convergence speed is improved.
