We derive the CRBs (Cramer Rao bound) for the joint estimation of the TOA (time of arrival) and the AOA (angle of arrival) in wideband (WB) MISO (multiple input single output) and MIMO (multiple input multiple output) systems. We consider both cases of orthogonal and non-orthogonal transmitted signals. We compare the CRBs obtained in SISO (single input single output), SIMO (single input multiple output),...
This paper presents a multiple-input multiple-output (MIMO) space-time geometrical channel model with hyperbolically distributed scatterers for a macrocell mobile environment. The model is based on a one-ring scattering assumption. This MIMO model provides statistics of the time of arrival (TOA) and direction of arrival (DOA). It is assumed that there is no line of sight (LOS) between the transmitter...
This paper introduces a general concept of a space time geometrical channel model with hyperbolically distributed scatterers for a macrocell mobile environment. This model provides statistics of the time of arrival (TOA) and direction of arrival (DOA). The proposed channel model is modified to multiple input multiple output (MIMO) model which characterizes the space and time-variance characters of...
