Wavelet-Based Noise Reduction in DVBT Systems

Problem Definition

Problem Description: The main problem that this project aims to address is the degradation of signal quality in Digital Video Broadcasting (DVB-T) systems due to noise interference. Noise is an unwanted signal that can alter the transmitted information and reduce the overall performance of the system. In terrestrial broadcasting, high transmitting sites are used to ensure a high bit rate over frequency selective channels, but noise still remains a major factor impacting signal quality. Traditional methods of noise reduction may not be efficient enough to completely remove noise from the system, leading to degraded signal quality at the receiver end. This project focuses on using a wavelet thresholding method to effectively reduce noise in DVBT systems.

The wavelet approach is expected to be more efficient in noise reduction compared to traditional methods. Therefore, the primary problem to be addressed using this project is the improvement of signal quality in DVBT systems by implementing a wavelet approach to remove noise interference from the signal. This would ultimately enhance the performance and reliability of digital television broadcasting and data transmission.

Proposed Work

The project titled "DVBT with wavelets transmission over noise channel for performance analysis" focuses on the use of Digital Video Broadcasting (DVBT) systems for digital television transmission and data broadcasting. The main issue addressed in this project is the presence of noise in the DVBT signal, which degrades the signal quality. To reduce this noise, a wavelet thresholding method is employed, which proves to be more efficient than traditional noise reduction approaches. The project involves the use of MATLAB software to analyze the noise channel in DVBT using wavelet transmission. By implementing a wavelet approach, the project aims to enhance the signal quality by removing unwanted noise.
