Abstract

This paper describes the concept of adaptive noise cancelling, an alternative method of estimating signals corrupted by additive noise or interference. A desired signal corrupted by additive noise can often be recovered by an adaptive noise canceller using the least mean squares (LMS) algorithm. This Adaptive Noise Canceller is then useful for enhancing the S/N ratio of data collected from sensors (or sensor arrays) working in noisy environment, or dealing with potentially weak signals. The principle advantages of the method are its adaptive capability, its low output noise, and its low signal distortion. The adaptive capability allows the processing of inputs whose properties are unknown. In this paper, the aim is to reduce the noise in speech signal and improve the quality of speech signal as well as to improve the efficiency of the data transmission and adding more feature without doing major changes. FPGA implementation of ANC done using Xilinx ise 9. 1 software and for synthesis use the Spartan 3 device.
