Abstract :
This paper investigates the performance of a number of direction-of-arrival (DOA) estimation algorithms in a wideband macrocellular channel using a dual-polarised antenna array. The signal data is obtained from a new spatial-temporal three-dimensional deterministic propagation model. The model was developed to meet the hierarchical network planning needs of third generation (3G) networks. Results show that a three-fold theoretical and two-fold practical improvement in DOA estimation accuracy can be achieved by exploiting information from a dual-polarised array
