Abstract

um método para detectar um impulso de comutação de sincronização usando um detector de potência em um sistema de duplexagem por divisão no tempo (tdd) inclui receber um sinal de entrada, detectar um nível de potência associado ao sinal de entrada usando um medidor de potência digita, e determinar uma configuração associada ao sinal de entrada. o método também inclui determinar que uma largura de impulso associada ao sinal de entrada é maior que um limite, determinar um deslocamento associado com uma configuração de subquadro especial, e gerar um impulso de sincronismo estimado. o método inclui adicionalmente formar um impulso de sincronismo regenerado, de sincronismo estimado e o impulso de sincronismo regenerado, determinar que o erro é menos que um limite, e prover uma detecção de bloqueio.
