Improvement of the Content Transmission in Broadcasting Systems: Potential Proposal to Rayleigh and Rician Multichannel MIMO Systems

Abstract

In the last years, the transmission of signals has been a widely approached theme, aiming the creation of methodologies that make channels increasingly efficient. Based on that, the present study implements a model based on discrete events applied to a broadcasting system entitled hybrid method, using the Simulink simulation environment of the MATLAB software. This study has the objective of improve the transmission of content, through a pre-coding process of bits applying discrete events in the signal before of the modulation process. This proposal brings a different approach, in which the signal transmission on the channel is realized in the discrete domain with the implementation of discrete entities in the process of bit generation. The results show better computational performance related to time and memory utilization related to the compression of the information, showing improvement 9.61 to 26,5%, respectively.
