Method for Reducing of Noise by Improving Signal-to-Noise-Ratio in Wireless LAN

The Signal to Noise Ratio (SNR) is one of the important measures for reducing the noise. It is a technique that uses a Linear Prediction Error Filter (LPEF) and an Adaptive Digital Filter (ADF) to achieve noise reduction in a speech and image degraded by additive background noise is proposed. Since a speech signal can be represented as the stationary signal over a short interval of time, most of speech signal can be predicted by the LPEF. This estimation is performed by the ADF which is used as system identification.
