In this paper, a nonlinear modified constant modulus algorithm (NMCMA) is proposed by applying a nonlinear transfer function (NTF) into modified constant modulus algorithm (MCMA), where the NTF makes the decision region of its cost function sharper so that NMCMA is more robust against the convergency error. The single layer in NMCMA simultaneously guarantees a comparably speedy convergency. Computer...
With the single-layer architecture and linear transfer function, constant modulus algorithm (CMA) cannot work well for the nonconvex and nonlinear cost function due to the convex decision region. To suppress the convergence error and improve the performance, the neural network constant modulus algorithm (NNCMA) is proposed by integrating CMA and neural network scheme. However, all existing NNCMAs...
Ambient noise caused by room acoustics usually degrades quality and reliability of speech recognition for the service robot application. In this paper, we propose enhancing the robustness of speech recognition for home service robots by combining blind equalization with classification. In particular, the linear predictive code (LPC) is used for feature extraction. The constant modulus algorithm (CMA)...
