In this paper, three different nominal Angle of Arrival (AoA) and Angular Spread (AS) estimators are compared. A single source transmitter through a Rayleigh channel scenario is considered. First, the Maximum Likelihood (ML) estimator is studied. Then, low-complexity estimators which are the Spread Root-MUSIC and the two-stage approach, are presented.(More)
In this paper, three different low-complexity maximum Doppler Spread (DS) estimators are compared. A single source transmitter through a Rayleigh channel scenario is considered. The first studied method is based on velocity estimation and correlation properties of narrow-band mobile communication channels. The second low-complexity considered approach is(More)
In this paper, we propose a new method to simultaneously estimate the maximum Doppler Spread (DS), the mean Angle of Arrival (AoA) and the Angular Spread (AS). To this end, the derivatives of the cross-correlation functions (DCCF) of the received signal at a Uniform Linear Array (ULA) are exploited. The Rayleigh channel model where the received signal AoAs(More)
