Abstract

With the objective of improving the transmission of content in wireless telecommunication systems, in simulation environment is proposed a precoding process of bits based in the application of discrete events in the signal before of the modulation process. The proposal brings a different approach of usual technical, 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 present work implements a model based on discrete events applied at a low level of abstraction in a wireless telecommunication system named hybrid method, being used the Simulink simulation environment of the MATLAB® software. In the simulation are considered advanced modulation format for signal transmission in an AWGN channel, and the studies are performed in different physical machines. The results show improvement of 9 to 30% in memory utilization, as also best computational performance as to simulation time. The extension of the results of this study has a strong impact on the methods performed in higher layers, being able to improve them even more, since this proposal acts on the bits.
