Site-specific wideband indoor channel modelling using ray-tracing software

Ray tracing (RT) software has been used to develop a site-specific autoregressive (AR) model for an indoor radio channel. A comparison is carried out between this model and that derived from the channel measurements. To enhance the congruence between the two models, an interpolation technique is applied to the RT raw data. It is concluded that a two-pole AR model can be derived from the RT software instead of the channel measurements. Results obtained from RT software avoid expensive and time consuming measurement process.
