Speech Enhancement using Kernel and Normalized Kernel Affine Projection Algorithm
The goal of this paper is to investigate the speech signal enhancement using Kernel Affine Projection Algorithm (KAPA ) and Normalized KAPA. The removal of background noise is very important in many applications like speech recognition, telephone conversations, hearing aids, forensic, etc. Kernel adaptive filters shown good performance for removal of noise. If the evaluation of background noise...
متن کاملSpeech Enhancement using Affine Projection Algorithm and Normalized Kernel Affine Projection Algorithm
The aim of the Speech Enhancement system is to improve the quality of noisy speech signal. This paper emphasize on enhancement of noisy speech by using Affine Projection Algorithm (APA) and Kernel Affine Projection Algorithm (KAPA). Noise is present everywhere in the environment, So Kernel adaptive filters are used to enhance noisy speech signal and shows the good improvement in increasing the ...
متن کاملSliding Window Generalized Kernel Affine Projection Algorithm Using Projection Mappings
Very recently, a solution to the kernel-based online classification problem has been given by the adaptive projected subgradient method (APSM). The developed algorithm can be considered as a generalization of a kernel affine projection algorithm (APA) and the kernel normalized least mean squares (NLMS). Furthermore, sparsification of the resulting kernel series expansion was achieved by imposin...
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 کاملThe fast affine projection algorithm
This paper discusses a new adaptive filtering algorithm called fast affine projections (FAP). FAP’s key features include LMS like complexity and memory requirements (low), and RLS like convergence (fast) for the important case where the excitation signal is speech. Another of FAP’s important features is that it causes no delay in the input or output signals. In addition, the algorithm is easily...
