Resumen

Cognitive radio is characterized by being a system capable of evaluating its electromagnetic environment and automatically adjusting its radio operating parameters, and modifying some system parameter to more optimal and favorable conditions. In this sense, in this work an adaptive control system of the transmitted power in the SDR platform is developed for wireless sensor networks, where the sensor node sends random data bits modulated in QPSK to the base station, which receives the data and proceeds to evaluate the SNR of the channel, and based on this parameter determines how much the transmitted power should adjust the sensor node. To carry out the power adaptation process, it uses the full duplex transmission mode on separate channels.
