This paper explains a methodology for beamforming of an ultrawideband signal (UWB). Tapped delay line (TDL) has been chosen as the beamformer structure and the channel environment considered is multipath and non line of sight in nature, compliant to IEEE 802.15.3a standards. The entire procedure for beamforming was done in the frequency domain owing to the nanosecond duration of ultrawideband pulses,...
In this paper coherent signal subspace method (CSM) is used to estimate the direction of arrival (DOA) of ultra wide band (UWB) signals in a multipath, non line of sight (NLOS) environment. As the name suggests it focuses the signal space of the wideband signal into a narrow subspace and the pseudospectrum of the resultant focused signal is calculated. The focusing frequency is calculated by minimizing...
