On the base of this reference model, a deterministic simulation model is developed by keeping the difference of correlation properties between reference and simulation model as smaller as possible. The correlation properties include temporal autocorrelation fimction (ACF), two-dimensional (2-D) space cross-correlation function (CCF) and frequency correlation function (FCF). The results show that although pinhole channel has good correlation properties, the channel capacity is very low because of the low rank of channel transform matrix.展开更多

文摘This article presents a general pinhole channel reference model based on the cause of pinhole effect. On the base of this reference model, a deterministic simulation model is developed by keeping the difference of correlation properties between reference and simulation model as smaller as possible. The correlation properties include temporal autocorrelation fimction (ACF), two-dimensional (2-D) space cross-correlation function (CCF) and frequency correlation function (FCF).
