“…The mean values, on the other hand, increase as the threshold decreases. Also, the values of both the excess delay and the RMS delay spread are much higher than those observed in single transmitter measurements, as reported in [11,7]. …”

“…In this final review of the current research development, some relevant parameters related to the multipath behavior of the channel, using field data collected in a real network were considered in (Guerra, 2005). Besides that, the reception conditions associated with a distributed transmission scheme together with an analysis of the influence of the specific environment were also addressed.…”

“…To evaluate the Root Mean Square Delay Spread (RDS) of measured channel, an urban and a semi-urban environment were chosen, in which three transmitters were responsible for covering the measurements of such regions. In order to determine which transmitters operated at each point chosen for testing, the measurements of the delay profile were obtained at points in the region, as defined in (Guerra, 2005), using the impulse response in the transmissions, since previously they already had the theoretical values of the impulse responses of each transmitter. In this way, it was possible to compare and conclude which transmitters were acting at each point.…”

Este artigo apresenta resultados do espalhamento de retardo, fornecendo em primeira mão uma revisão bibliográfica completa aplicada à Televisão Digital Terrestre utilizada em esquemas de transmissão distribuída. Um levantamento da situação atual do desenvolvimento da pesquisa é obtido a partir de uma possível tendência recomendada por uma campanha de medição realizada em uma rede de frequência única urbana com dois transmissores sincronizados. A discussão de possíveis questões relacionadas às condições de recepção é considerada e a constante necessidade de atender aos requisitos técnicos modernos, como eficiência espectral e flexibilidade do sistema, também é abordada. Resultados teóricos, de simulação computacional, experimentais e de ensaios de campo são apresentados neste artigo, confirmando as melhorias associadas às redes de diversidade de fontes.

“…While the fixed television has been examined by the measurement results based on an empirical model [15][16][17][18], the results found that the carrier to noise ratio (C/N) minimizes to less than the requirement for the television receiver. Even though the C/N parameter is important, the path loss measurement is also important to predict the density of multipath fading, especially in a single-frequency network (SFN) [19,20]. Therefore, the field trial has been introduced [21], where path loss varies in a range from 60 dB to 120 dB for Gaussian and Rician channels.…”

The aim of this paper was to propose quantitative measurement of path loss model adaptation in urban radio propagation for a second-generation, terrestrial digital video broadcasting standard (DVB-T2) system. The measurement data was analyzed using data processing based on the least squares (LS) method to verify the probabilistic quantitation of realistic data measurement such as mean error (ME), root mean square error (RMSE), and standard deviation of error (SD), as well as relative error (RE). To distinguish the experimental evaluation, the researchers compared between the conventional Hata path loss model and the proposed model. The result showed that path loss based on the proposed model was more accurate in predicting the quantitative measurement of propagation data properly.
