"OFDM System Performance Analysis Using Digital Video Broadcasting Approach"

Problem Definition

Problem Description: One of the major problems in wireless communication systems is the issue of multipath propagation delay and fading that arise in Orthogonal Frequency Division Multiplexing (OFDM) systems. These factors can significantly degrade the quality of service provided to end users by causing errors in data transmission and reducing the reliability of the communication link. This project aims to address this problem by implementing a Digital Video Broadcasting (DVB-T) approach in OFDM systems. By broadcasting a multiplex of various services using DVB-T, the project aims to improve the spectral efficiency, reliability, and capacity of the wireless communication system. By utilizing this approach, the project seeks to minimize the impact of multipath propagation delay and fading, ultimately enhancing the quality of service delivered to end users.

Proposed Work

The project titled "Digital video broadcasting approach in OFDM system in wireless communication" focuses on improving the quality of service in wireless communication by utilizing Orthogonal Frequency Division Multiplexing (OFDM) techniques.
