Abstract

In this paper, a new channel model is proposed. Since it is spatially and temporally correlated simultaneously, this new model is well consistent with the real environment of array antenna applications. The widely used sum of scattered waves and the measurement-based model have a common drawback of imperfect statistical properties, reducing the reliability of simulation results. The new model (spatially and temporally correlated fading model [STCFM]) is derived rigorously in the spatiotemporal domain so that it can provide high accuracy for the evaluation of the array antenna system. Simulation results show that direction of arrival (DOA) and angle of spread (AOS) are well defined in STCFM, BPSK with two-branch maximal ratio combining and DBPSK with differential detection are considered to verify the spatial and temporal correlation robustness of the new model, respectively. As is shown, the simulation results agree well with the theory
