A interferência entre símbolos (ISI) é uma fonte significativa de degradação em muitos sistemas de comunicação digital, incluindo nosso sistema de comunicação proposto para regiões não distantes, usando antenas de grande conjunto na banda de ondas milimétricas, em que a principal causa do ISI pode ser atribuída às diferenças de atraso de caminho. entre os elementos de um conjunto de antenas. Este artigo propõe um método quantitativo para avaliar o ISI estimado a partir da distribuição de campo próximo medida do conjunto de antenas. A influência da uniformidade na distribuição do campo de abertura no ISI é discutida e comparada com uma excitação idealmente uniforme. A confiabilidade do método proposto é verificada através de uma comparação com outro método baseado em medições diretas da transmissão entre as antenas reais. Finalmente, a relação sinal-ruído mais interferência é avaliada com base nos resultados estimados do ISI e o ISI é mostrado como a causa dominante da degradação na zona de recepção do sistema.

Abstract: Intersymbol interference (ISI) is a significant source of degradation in many digital communication systems including our proposed non-far region communication system using large array antennas in the millimeter-wave band in which the main cause of ISI can be attributed to the path delay differences among the elements of an array antenna. This paper proposes a quantitative method to evaluate the ISI estimated from the measured near-field distribution of the array antenna. The influence of the uniformity in the aperture field distribution in ISI is discussed and compared with an ideally uniform excitation. The reliability of the proposed method is verified through a comparison with another method based on direct measurements of the transmission between the actual antennas. Finally, the signal to noise plus interference is evaluated based on the estimated ISI results and ISI is shown to be the dominant cause of the degradation in the reception zone of the system.
