Propagation measurements of mobile radio channel over sea at 5.9 GHz

A radio channel measurement campaign with a maximum distance of 2.6 km was performed in China. In this paper, a detailed description of the channel measurement campaign including antenna setups, channel sounder configurations and other related info is given. The received signal level (RSL) is shown and compared with the Plain Earth Loss model (PEL), the ITU-R P.1546-2 model (ITU-R) and the Round Earth Loss model (REL). It can be found that the REL model matches the measured RSL best according to the values of the Root Mean Square Error (RMSE). The Power-delay profiles (PDPs) are demonstrated, from which the mean excess delay and the RMS delay spread are extracted. It can be found that the 90% of the mean excess delay and the RMS delay spread are within 4.3 ns and 113.3 ns according the corresponding Cumulative Distribution Functions (CDF), respectively. The Akaike Information Criterion (AIC) is used to estimated the best-fit amplitude distribution of the small-scale fading. The Two-Wave with Diffuse power (TWDP) model is found to be the best-fit model with more than 90% incident percentage in the whole route.
