Um projeto e análise adequados de futuros sistemas de comunicação sem fio de banda larga requerem um modelo preciso de canal de rádio. Este modelo caracteriza as características espaciais e temporais do canal. Este artigo investiga a modelagem espaço-temporal de canais baseada em uma abordagem de traçado de raios. Os canais temporais são caracterizados por um perfil de atraso. A mediana estatística e a faixa de flutuação de desvanecimento dos perfis de atraso são previstas a partir do traçado de raios, incorporando a abordagem de fase aleatória. Um alto nível de concordância entre os resultados previstos e os medidos é observado na verificação. A resposta ao impulso do canal espaço-temporal (CIR) prevista a partir do traçado de raios também é transformada para ter largura de banda limitada e características de largura de feixe limitadas. A aplicabilidade desta transformação também é verificada pela comparação com a medição. Essas verificações preparam o terreno para o uso de abordagens de rastreamento de raios para avaliar o desempenho do sistema em ambientes reais.

Abstract: A proper design and analysis of future wideband wireless communication systems require an accurate radio channel model. This model is claimed to characterize both the spatial and temporal channel characteristics. This paper investigates the spatio-temporal channel modeling based on a ray-tracing approach. The temporal channels are characterized by a delay profile. The statistical median and fading-fluctuation range of delay profiles are predicted from ray tracing by incorporating the random phase approach. A high level of agreement between predicted results and measured ones is observed in the verification. The spatio-temporal channel impulse response (CIR) predicted from ray tracing is also transformed to have limited band-width and limited beam-width characteristics. The applicability of this transformation is also verified by the comparison with measurement. These verifications prepare the ground for the use of ray-tracing approaches to evaluate system performance in real environments.
