With the objective of improving the transmission of content in telecommunication systems, in simulation environment is proposed a pre-coding 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. In general, the simulation tools for a model of telecommunication transmission system are based on continuous and discrete signals. The present work implements a model based on discrete events applied at a low level of abstraction in a 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. The results show improvement of 9 to 22% in memory utilization, as also best computational performance.
