Nas últimas décadas, surgiram dispositivos de tecnologia de rádio cognitivo, que podem ajustar os seus parâmetros de funcionamento de acordo com os dados que foram detectados a partir do ambiente circundante, onde as redes de rádio cognitivo gerem um processo de partilha de espetro entre vários utilizadores, classificando-os para um utilizador primário, que é o proprietário da licença e tem a autoridade total para utilizar a largura de banda, e o utilizador secundário, tem o direito de utilizar a largura de banda, mas sem influenciar o utilizador principal. Alguns factores desempenham um papel importante na determinação da eficiência e do desempenho do sistema de rádio cognitivo, um dos quais é a taxa de erro de bits dos dados transmitidos, que deve ser tão baixa quanto possÃvel para obter os melhores resultados.
