We propose a new simple and accurate approach to estimate the Doppler spread which is a key parameter in the context of wireless communication systems. This new approach stems from the well known fact that the crosscorrelation of the channel is a weighted summation of monochromatic plane waves (or inverse Fourier transform of its power spectral density). In the case of Doppler spread, these plane...
We estimate the angular spread (AS) and the nominal angle of arrival (AoA) of a locally scattered source using a uniform linear array (ULA) of sensors. First, we use Taylor series expansions to transform this problem into the localization of two point sources as it has been proposed in the literature. Based on the resulting approximate form of the covariance matrix, we directly retrieve analytical...
We present a new technique to localize multiple scattered sources and estimate their angular spreads (ASs). We take into account the partial stationarity of the channel and propose a two-stage approach to estimate the ASs and the nominal angles of arrival (AoAs) of the sources. First, we blindly estimate the channels over several data blocks regularly spaced by intervals larger than the coherence...
