In Speech processing Signal to Noise (SNR )Ratio plays an important role for Noise cancellation. here an attempt is made to evaluate SNR for given Noisy Speech signal using adaptive technique Binary LMS algorithm. In this proposal , Introduces the two control parameters of the Adaptive Algorithm rather than one control parameter as in case of LMS Algorithm. Also comparirison is made with respec...

In this paper, A variable step-size filtered-X LMS (VSS-FXLMS) algorithm is first introduced to replace the filtered-X LMS (FXLMS) algorithm in the main controller of conventional narrowband ANC system, and extensive simulations reveal that this ANC system may also suffer from significant performance degradation in the presence of Frequency mismatch (FM), although it acts better in the key char...

We have designed and simulated an adaptive line enhancer system for conferencing. This system is based upon a leastmean-square (LMS) and recursive adaptive algorithm (RLS) Performance of ALE is compared for LMS&RLS algorithms.

In this paper, Least Mean Square (LMS) adaptive noise reduction algorithm is proposed to enhance the speech signal from the noisy speech. In this, the speech signal is enhanced by varying the step size as the function of the input signal. Objective and subjective measures are made under various noises for the proposed and existing algorithms. From the experimental results, it is seen that the p...

A new Lp-norm constraint least mean square (Lp-LMS) algorithm with new strategy of varying p is presented, which is applied to system identification in this letter. The parameter p is iteratively adjusted by the gradient method applied to the root relative deviation of the estimated weight vector. Numerical simulations show that this new algorithm achieves lower steady-state error as well as eq...

An improvement of Signal-to-Interference Ratio (SIR) at the base station of a wireless communication system can be obtained using a suitable choice of an array antenna. In this paper we consider Concentric Circular Antenna Array (CCAA) which can be used for adaptive antenna systems. A new adaptive algorithm, called least mean square-least mean Square (LLMS) algorithm, has been proposed for diff...
