Implementation of Noise Cancellation using Adaptive Algorithms in GNU Radio

Abstract

The demand for wireless communication system design is on the rise recent days. When data is transferred through a wireless channel, the noise on the channel has a larger probability of affecting the information. The suggested project attempts to aid in the reduction of noise through the use of an adaptive filter in order to ensure reliable communication. In this way noise cancellation plays an important role in digital communication. GNU Radio is an open framework for building real-time signal processing applications on low-cost single-board computers. C++ and Python language is suitable for backend in GNU radio. MATLAB and python simulation for different algorithms helps in analysing reduced noise and rate of convergence.
