Abstract

Patente de Invenção:<B>"TECNOLOGIA DE COMUNICAçãO DE PORTADORA ACUMULADA DE TONS MúLTIPLOS DISCRETOS"<D>. Um sistema de comunicação de espectro de dispersão de "portadora acumulada" (10) baseado na dispersão de domínio de freq³ência que multiplica uma representação de domínio de tempo de um sinal de banda de base por um conjunto de ondas portadoras senoidais complexas sobrepostas, ou acumuladas. Em uma modalidade preferida (10), a disperção energiza os escaninhos de uma grande transformada de Fourier rápida (FFT). As topologias de rede de Ponto para Multiponto e de Multiponto para Multiponto (sem nodos) são possíveis. Um método de anulação de código é incluído para o cancelamento de interferência e separação de sinal melhorada explorando a diversidade espectral das várias fontes (11). O sistema básico (10) pode ser estendido para incluir os métodos de anulação de matriz de antenas de elementos múltiplos (26, 18) também para o cancelamento de interferência e separação de sinal melhorada utilizando a separação espacial. Tais métodos permitem os sistemas de transmissão diretivo e retrodiretivo que adaptam ou podem ser adaptados ao ambiente de rádio. Tais sistemas são compatíveis com os formatos de largura de banda sob demanda e de modulação de ordem mais alta e utilizam os algoritmos de adaptação de não-dispersão avançados (SINR máximo).
