Abstract

estação móvel, método de transmissão e sistema de comunicação. a presente invenção refere-se a um sistema de comunicação incluindo múltiplas estações móveis e uma estação de base. a estação móvel mapeia um canal piloto compreendendo um código cazac para um sinal incluindo múltiplos componentes de frequência dispostos em intervalos regulares em uma determinada banda de frequência e transmite um sinal de transmissão incluindo o sinal de acordo com a informação de programação. a estação móvel executa o mapeamento tal que o seu sinal de transmissão e os sinais de transmissão de outras estações móveis usando bandas de frequência diferentes se tornam ortogonais um em relação ao outro em um eixo de frequência. a estação de base calcula a correlação entre um sinal recebido e uma réplica do canal piloto, executa a estimativa do canal e de modula o sinal recebido com base no resultado da estimativa do canal. a estação de base gera a réplica do canal piloto mapeando um canal piloto compreendendo um código cazac para um sinal incluindo múltiplos com ponentes de frequência organizados em intervalos regulares em uma deter minada banda de frequência.
