Abstract
aspectos da presente revelação podem incluir, por exemplo, receber, por um elemento de rede de um sistema de antena distribuída, um sinal de referência e um primeiro sinal modulado em uma primeira frequência de portadora, em que o primeiro sinal modulado inclui os primeiros dados de comunicações fornecidos por uma estação de base e direcionados a um dispositivo de comunicação móvel. o elemento converte o primeiro sinal modulado na primeira frequência de portadora para o primeiro sinal modulado em um primeiro segmento espectral com base em um processamento de sinal analógico do primeiro sinal modulado e com a utilização do sinal de referência para reduzir a distorção durante a conversão. o elemento de rede transmite sem fio o primeiro sinal modulado no primeiro segmento espectral para o dispositivo de comunicação móvel. outras modalidades são reveladas.Aspects of the present disclosure may include, for example, receiving, by a network element of a distributed antenna system, a reference signal and a first modulated signal at a first carrier frequency, wherein the first modulated signal includes the first data. communications provided by a base station and directed to a mobile communication device. The element converts the first modulated signal at the first carrier frequency to the first modulated signal into a first spectral segment based on analog signal processing of the first modulated signal and using the reference signal to reduce distortion during conversion. the network element wirelessly transmits the first modulated signal in the first spectral segment to the mobile communication device. other modalities are revealed.
