Abstract :
A common practice to avoid the attenuation presented in a wireless communication system is using fading mitigation techniques. Examples of those techniques are the adaptive systems. The proposal of this article is about a system that can switch its transmission and reception characteristics according the bit error rate (BER) between the sent and received data. The system (simulated in Matlab) will commute in a certain value that will be established by the user. The characteristics of the system (modulation and coding) are the same of that shown in the 802.16 standard. In this way, an adaptive system was created with two modes: one with only modulation (16QAM) and the other with modulation (16QAM) and coding (Reed Solomon (64,48)). The BER value is established by the user, getting a more efficient system according to the necessities
