The present study contrasts the benefits of using different coding methods within a communication protocol, in terms of its reliability. For this purpose, a protocol was designed in the link layer (BTLCP), with which the parameter measured BER of various combinations of modulation and coding techniques. The source of data in this system was a set of brainwave studies sampled from outside, and also electroencephalographic signals generated by a proprietary model. This set of conditions was implemented and simulated within a specific application of discrete event simulation and matrix calculus (OpenTonitruum). The test results were highly variable with respect to the coding and low variation in the modulation ratio, demonstrating that the effect of the different phase modulation techniques is indifferent, coding techniques being really influential in the performance. Furthermore, we found that possesses turbocodes coding error rate lower than the rest, increasing the reliability of the protocol
