Abstract

Separação de sinais estatisticamente independentes através do uso de códigos espalhados. 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 difusor de código é ligado aos N elementos de antena de modo a decodificar as ao menos N somatórias diferentes dos M sinais fonte. Cada uma das N somatórias diferentes inclui k códigos de modo a fornecer k somatórias diferentes dos M sinais fonte associados a estas. Um processador de separação de sinais estatisticamente independentes forma uma matriz de composição a qual compreende até ao menos kN diferentes somatórias dentre os M sinais fontes, e separa os sinais fonte desejados da matriz de composição. A matriz de composição apresenta uma graduação igual a até kN.Separation of statistically independent signals through the use of scattered codes. 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 code diffuser is connected to the N antenna elements in order to decode at least N different summaries from the M source signals. Each of the different N summaries includes k codes to provide k different summaries of the associated M source signals. A statistically independent signal separation processor forms a composition matrix which comprises at least kN different summation among the M source signals, and separates the desired source signals from the composition matrix. The composition matrix has a grade of up to kN.
