Analysis of Raised Cosine Filtering in Communication Systems

In this era of wireless communication systems inter symbol interference (ISI) is a major issue. In this paper the inter symbol interference rejection capability of a raised cosine filter (RCF) is analyzed. Simulation is done for analyzing the importance of rolloff factor and its selection in a raised cosine filter for evaluating the desired response. Communication toolbox in CAD tool MATLAB is being employed for the simulation.
