Alcançar o desempenho ideal com complexidade mínima são problemas conflitantes encontrados na construção de receptores. Neste artigo, para resolver o problema, propomos salto espacial com feixe setorial que utiliza um receptor equalizador Viterbi. É apresentada a redução do número de conjuntos de circuitos de RF, a complexidade do sistema e a diminuição da carga computacional do equalizador de Viterbi através do uso de salto espacial com feixe setorial. Isto é conseguido usando uma antena com feixe setorial que limita o número de caminhos no ambiente de canal multipercurso. Este artigo descreve cada componente-chave que compõe o sistema e discute a aplicação da comunicação FH-SS. Supõe-se que o canal seja um canal de propagação industrial interno, como aqueles encontrados em uma fábrica, onde é necessária alta confiabilidade e existem muitos caminhos múltiplos complexos. Confirmamos através de simulação que a equalização de Viterbi utilizando menos complexidade computacional pode ser obtida. Verifica-se que existe um compromisso entre complexidade e desempenho do sistema. Através da discussão do consumo de energia, custo e desempenho do BER, mostramos que o sistema proposto atinge um desempenho aceitável ao mesmo tempo que possui uma baixa complexidade do sistema.

Abstract: Achieving optimal performance with minimal complexity are conflicting problems encountered in constructing receivers. In this paper, to solve the problem, we propose sector beamed space hopping which utilizes a Viterbi equalizing receiver. Reduction of the number of RF circuit sets, system complexity and decreasing the computational burden of the Viterbi equalizer through the use of sector beamed space hopping is presented. This is achieved using a sector beamed antenna which limits the number of paths in the multipath channel environment. This paper describes each key component which comprises the system and discusses the application of FH-SS communication. The channel is assumed to be an industrial indoor propagation channel, such as those found in a factory, where high reliability is required and many complex multipaths exist. We confirm through simulation that Viterbi equalization using less computational complexity can be obtained. It is found that there exists a trade off between system complexity and performance. Through the discussion of power consumption, cost and BER performance, we show that the proposed system achieves acceptable performance while having a low system complexity.
