Avoiding Explicit Regularisation in Affine Projection Algorithms for Acoustic Echo Cancellation
نویسندگان
چکیده
The so–called affine projection algorithm has become a popular tool in the context of acoustic echo cancellation. Regularisation is an absolute necessity in an affine projection algorithm to avoid near end noise amplification. This paper describes a method to achieve zero overhead regularisation while allowing stable algorithms to be employed to update the inverse covariance matrix that is used in these algorithms.

A Family of Selective Partial Update Affine Projection Adaptive Filtering Algorithms
In this paper we present a general formalism for the establishment of the family of selective partial update affine projection algorithms (SPU-APA). The SPU-APA, the SPU regularized APA (SPU-R-APA), the SPU partial rank algorithm (SPU-PRA), the SPU binormalized data reusing least mean squares (SPU-BNDR-LMS), and the SPU normalized LMS with orthogonal correction factors (SPU-NLMS-OCF) algorithms...
متن کاملThe Variable Step-Size Gauss-Seidel Pseudo Affine Projection Algorithm
In this paper, a new pseudo affine projection (AP) algorithm based on Gauss-Seidel (GS) iterations is proposed for acoustic echo cancellation (AEC). It is shown that the algorithm is robust against near-end signal variations (including double-talk). Keywords—pseudo affine projection algorithm, acoustic echo cancellation, double-talk.
متن کاملMultichannel affine and fast affine projection algorithms for active noise control and acoustic equalization systems
In the field of adaptive signal processing, it is well known that affine projection algorithms or their low-computational implementations fast affine projection algorithms can produce a good tradeoff between convergence speed and computational complexity. Although these algorithms typically do not provide the same convergence speed as recursive-least-squares algorithms, they can provide a much ...
متن کاملNew Proportionate Affine Projection Algorithm
A new proportionate-type affine projection algorithm with intermittent update of the weight coefficients is proposed. It takes into account the “history” of the proportionate factors and uses a fast recursive filtering procedure. Also, the effect of using dichotomous coordinate descent iterations is investigated. Simulation results indicate that the proposed algorithm has improved performance a...
متن کاملSubband Affine Projection Algorithm for Acoustic Echo Cancellation System
We present a new subband affine projection (SAP) algorithm for the adaptive acoustic echo cancellation with long echo path delay. Generally, the acoustic echo canceller suffers from the long echo path and large computational complexity. To solve this problem, the proposed algorithm combines merits of the affine projection (AP) algorithm and the subband filtering. Convergence speed of the propos...
