The aquatic environments of the Pearl River Delta in Southern China are subjected to contamination with various industrial chemicals from local industries. In this paper, the occurrence, seasonal variation and spatial distribution of alkylphenol octylphenol (OP) and nonylphenol (NP) in river surface water and sediments in the runoff outlets of the Pearl River Delta were investigated. NP and OP were...
Interdependences of radio-channel model parameters, being observed in some measurement data, should be reproduced by the model. For that purpose the statistical correlation is often used. From the same wideband multiple-input and multiple- output (MIMO) channel data, estimated correlation between large-scale propagation parameters (e.g. delay spread and shadow fading) could be different due to non-uniqueness...
Statistical channel models are attractive for their simplicity but sometimes lack in precision. In order to improve modelling accuracy, statistical model parameters, which are dependent on the environment, are extended to include spatial and temporal correlation. In outdoor scenarios these parameters are assumed constant over "large" areas of several wavelengths hence the name large scale...
In this paper double-directional wideband channel measurements at 5.2 GHz and 120 MHz bandwidth for hot spot outdoor and indoor scenarios are presented. Statistical analysis based on the measurements derive spatial and temporal parameters for the recently published WINNER1 channel model. The focus is on channel models for link level evaluation and radio network planning, whereby the tapped delay line...
The primary goal of this paper is through examining a set of measurement data to show that the spatial variation properties of large scale parameters can well be expressed by the exponential decaying function, as proposed by Algans et al. (2002), but with quite a small decorrelation distance. The large scale parameters include large scale fading and delay spread as well as azimuth spreads at the transmitter...
