Neste artigo, um sistema de rádio em fibra (ROF) de baixo custo para um sistema de comunicação de veículos rodoviários na banda de 36 GHz (RVCS) é proposto e demonstrado. Componentes ópticos para sistemas de transmissão de banda base de 10 Gb/s, que estão cada vez mais baratos, são usados no sistema proposto. O sinal é transmitido no link óptico na forma de um sinal de frequência intermediária (IF) da banda de 5.8 GHz. O terceiro subharmônico de uma onda osciladora local (LO) é transmitido simultaneamente com o sinal IF da estação central para as estações remotas (RSs). Este esquema permite a realização de RSs sem sintetizadores dispendiosos de ondas milimétricas. Em tal configuração, a influência da distorção de intermodulação entre o sinal IF e o subharmônico LO e a degradação da relação portadora-ruído (CNR) poderia ser um problema, e assim foram realizadas análises e experimentos. Foi esclarecido que a compressão da faixa dinâmica causada pela transmissão simultânea era pequena. A triplicação da frequência do LO degradou o CNR do LO; entretanto, esse efeito foi compensado pelo aumento do índice de modulação óptica (OMI) do subharmônico LO. O aumento do OMI do subharmônico LO provou não ter influência analítica e experimental nas características IM3 do sinal de RF. O sistema de baixo custo proposto provou ter características suficientes para RVCS de ondas milimétricas.

Abstract: In this paper, a low-cost radio-on-fiber (ROF) system for a 36 GHz band road-vehicle communication system (RVCS) is proposed and demonstrated. Optical components for 10 Gb/s baseband transmission systems, which are becoming lower in cost, are used for the proposed system. The signal is transmitted in the optical link in the form of an intermediate frequency (IF) signal of the 5.8 GHz band. The third subharmonic of a local oscillator wave (LO) is transmitted simultaneously with the IF signal from the central station to the remote stations (RSs). This scheme enables the realization of RSs without costly millimeter-wave synthesizers. In such a configuration, the influence of intermodulation distortion between the IF signal and the LO subharmonic and degradation of the carrier-to-noise ratio (CNR) could possibly be a problem, and so an analysis and experiments were carried. It was clarified that the compression of dynamic range caused by the simultaneous transmission was small. Frequency tripling of the LO degraded the CNR of the LO; however, this effect was compensated for by increasing the optical modulation index (OMI) of the LO subharmonic. Increasing the OMI of the LO subharmonic proved to have no influence on the IM3 characteristics of the RF signal analytically and experimentally. The proposed low-cost system proved to have sufficient characteristics for millimeter-wave RVCS.
