dc.description.abstractUltra wideband (UWB) systems are expected to coexist with narrowband systems as well as other UWB systems. By estimating the direction of arrival of the multipaths, one would be able to limit the transmission to these directions and limit the interference to other systems. The focussing of subspaces is used to improve the resolution performance in direction of arrival estimation of wideband signals. The focussing matrix is calculated based on initial coarse estimation of DOA. The error in initial estimation results in an irreducible bias in final estimated DOA. By making use of the known pilot signals in Wimedia systems, a new focussing scheme is proposed in this paper that does not require coarse estimation. Computer simulation experiments validating this scheme are also presented. The bias in final estimation is drastically reduced. © 2010 IEEE.
