The future use of cellular radio systems incorporating relay links is viewed [1–3] as key to the satisfaction of ever-increasing demands for greater capacity, while maintaining installation and operating costs at manageable levels. However, because of the scarcity of published propagation measurements on relay channels, channel models that have heretofore been used to support the claimed advantages...
A procedure for the analysis of narrowband fast fading data with statistically non-stationary characteristics is proposed and applied to data obtained from wideband radio propagation experiments involving two-hop relay channels at 2.25 GHz. The reported experiments were conducted from two channel sounder base station sites in Ottawa to enable a study of the characteristics of relay links in urban...
A stronger and general sufficient condition for the asymptotic normality of MIMO channel eigenvalues and its capacity is given. Physical interpretation of this condition is discussed. Simple alternative conditions, which do not require eigenvalue decomposition, are proposed. It is demonstrated that some popular correlation matrix models satisfy these conditions. In many cases, the convergence to the...
