Este artigo propõe um novo modem de espalhamento espectral (SS) para sistemas de comunicação via satélite de acesso aleatório que emprega filtros digitais casados. O modem proposto emprega uma estrutura paralela para garantir a detecção da chegada de pacotes. A detecção de temporização de código com uma combinação de um detector grosseiro e um detector de erro fracionário reduz a taxa de amostragem enquanto mantém o desempenho do BER. Um esquema de multiplexação piloto em símbolo também é proposto para sincronização de portadora rápida e estável com um hardware simples. Uma avaliação de desempenho mostra que o modem proposto atinge a probabilidade de detecção de erros UW de 10-4 no Eb/No de 0dB. O desempenho geral do BER alcançado em experimentos está de acordo com a simulação.

Abstract: This paper proposes a novel spread spectrum (SS) modem for random access satellite communication systems that employs digital matched filters. The proposed modem employs a parallel structure to ensure detection of packet arrival. Code timing detection with a combination of a coarse detector and a fractional error detector reduces the sampling rate while maintaining the BER performance. An in-symbol pilot multiplexing scheme is also proposed for fast and stable carrier synchronization with a simple hardware. A performance evaluation shows that the proposed modem achieves the UW miss-detection probability of 10-4 at the Eb/No of 0 dB. The overall BER performance achieved in experiments well agrees simulation.
