Abstract
Separação de sinais estatisticamente independentes com o uso de elementos correlatos de antenas. 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 correlatos de modo a receber ao menos N somatórias diferentes para os M sinais fontes, com M e N sendo maiores do que 1. O receptor é ligado ao feixe de antenas de modo a receber ao as menos N somatórias diferentes dos M sinais fonte. Um processador de separação de sinais estatisticamente independentes é ligado ao receptor de modo a formar uma matriz de composição compreendendo até as ao menos N somatórias diferentes dentre os M sinais fonte, e para separar os sinais fonte desejados a partir da matriz de composição. A matriz de composição apresenta uma graduação igual à até ao menos N.Separation of statistically independent signals using correlated antenna elements. A communication device which separates source signals from M signal sources, the device including an antenna array comprising N correlated antenna elements so as to receive at least N different summaries for M source signals, with M and N being greater than 1. The receiver is connected to the antenna array so as to receive at least N sum different from M source signals. A statistically independent signal separation processor is coupled to the receiver to form a composition matrix comprising up to at least N different summaries from the M source signals, and to separate the desired source signals from the composition matrix. The composition matrix has a rating equal to at least N.
