Abstract

Separação de sinais estatisticamente independentes através do uso dos componentes "1" e "Q". Um dispositivo de comunicação, o qual separa os sinais fonte provenientes de M fontes de sinal, o dispositivo incluindo uma formação de antenas compreendendo N elementos de antena para formar ao menos N feixes de antena para receber ao menos N diferentes somatórias dos M sinais fontes. Um respectivo módulo em fase e em quadratura é ligado a jusante em relação a cada elemento de antena de modo a separar cada um das N somatórias diferentes dos M sinais fonte recebidos por meio de cada conjunto de módulo em fase e em quadratura. Um processador de separação de sinais estatisticamente independentes forma uma matriz de composição a qual compreende até ao menos 2N diferentes somatórias dentre os M sinais fontes, com cada conjunto de componentes em fase e em quadratura fornecendo duas entradas para a matriz de composição. A matriz de composição apresenta uma graduação igual a até 2N. Os sinais fonte desejados são separados da matriz de composição pelo processador de separação de sinais estatisticamente independentes.Separation of statistically independent signals through the use of components "1" and "Q". A communication device which separates source signals from M signal sources, the device including an antenna array comprising N antenna elements to form at least N antenna beams to receive at least N different summaries of M source signals. A respective in-phase and quadrature module is connected downstream of each antenna element to separate each of the different N summaries from the M source signals received by each in-phase and quadrature module set. A statistically independent signal separation processor forms a composition matrix which comprises at least 2N different summation among the M source signals, with each set of phase and quadrature components providing two inputs to the composition matrix. The composition matrix has a rating of up to 2N. The desired source signals are separated from the composition matrix by the statistically independent signal separation processor.
