Abstract

"TRANSMISSOR E RECEPTOR DE SINAIS DE RáDIO, DISPOSITIVO E PROCESSO DE COMUNICAçãO E PROCESSO DE RECEBER UM SINAL DE RáDIO A PARTIR DE UMA ESTAçãO BASE". Um dispositivo de comunicação inclui um transmissor ( 21 ) e receptor. O transmissor ( 21 ) inclui um codificador M-ário ( 23 ) configurado para gerar um número M-1 de símbolos distintos cada um compreendendo k bits. M é igual a 2k e k é um número inteiro positivo. O transmissor ( 21 ) também inclui um gerador de código ( 25 ) configurado para produzir seq³ência de palavra código de propagação de espectro baseada nos símbolos gerados pelo codificador M-ário e baseados sobre primeiro e segundo polinómios de código de Gold. O transmissor ( 21 ) transmite um sinal de rádio baseado nas seq³ências de palavra código de propagação de espectro para um receptor. O receptor inclui um primeiro registrador de deslocamento ( 81 ) configurado para receber um sinal de entrada gerado baseado no sinal de rádio recebido e um segundo registrador de deslocamento ( 83 ) configurado para receber e deslocar circularmente uma seq³ência de palavra código localmente gerada que é idêntica à seq³ência de palavra código usada para codificar os símbolos."TRANSMITTER AND RECEIVER OF RADIO SIGNALS, DEVICE AND COMMUNICATION PROCESS AND PROCESS OF RECEIVING A RADIO SIGNAL FROM A BASE STATION". A communication device includes a transmitter (21) and a receiver. The transmitter (21) includes an M-ary encoder (23) configured to generate an M-1 number of distinct symbols each comprising k bits. M is equal to 2k and k is a positive integer. The transmitter (21) also includes a code generator (25) configured to produce spectrum propagation code word sequence based on the symbols generated by the M-ary encoder and based on first and second Gold code polynomials. The transmitter (21) transmits a radio signal based on the spectrum propagation code word sequences to a receiver. The receiver includes a first shift register (81) configured to receive a generated input signal based on the received radio signal and a second shift register (83) configured to receive and circularly shift a locally generated codeword sequence that is identical to the codeword sequence used to encode the symbols.
