Abstract

um terminal de usuário recebe um sinal de dados de enlace a jusante, um sinal de referência de demodulação para demodular o sinal de dados de enlace a jusante e um sinal de enlace a jusante incluindo um sinal de controle de enlace a jusante; calcula um valor de estimativa de canal usando o sinal de referência de demodulação; demodula o sinal de dados de enlace a jusante usando o valor de estimativa de canal; e demodula o sinal de controle de enlace a jusante utilizando o valor de estimativa de canal calculado a partir do sinal de referência de demodulação mapeado para um símbolo antes de um símbolo para o qual o sinal de controle de enlace a jusante é mapeado em um subquadro.
