Abstract

"MéTODO, TRANSMISSOR E RECEPTOR PARA UMA COMUNICAçãO DIGITAL DE ESPECTRO DIFUSO PELA MODULAçãO DE SEQUêNCIA COMPLEMENTAR DE GOLAY". O espectro da freq³ência de um sistema de transmissão ampliado no transmissor (1) por meio da codificação dos bits de informações por meio de pares de seq³ências complementares de Golay. O espectro é recebido no receptor (2 ), onde é passado através de um filtro adaptado às características das ditas seq³ências, o que torna possível detectar os níveis digitais que correspondem às informações transmitidas originais. Se n pares de seq³ências ortogonais, A amplitudes para modular os dados e a modulação N-PSK são utilizadas, é possível obter uma taxa de transmissão (C) de: C= 1/2 .<sym> . log~ 2~A . log~ 2~N . (B/2) bits/s. onde B é a largura de faixa de zero a zero ampliada utilizada, em Hertz. Torna-se possível melhorar a qualidade em comparação com outros sistemas de comunicação digitais utilizando tecnologias de espectro difuso e CDMA, obtendo um ganho de processamento independente da taxa de transmissão.
