Doppler and angular spreads estimation using the derivatives of the cross-correlation functions

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 follow a Gaussian angular distribution is considered. Simulation results show that, the proposed approach offers better accuracy for maximum DS than the algorithm developed in [1]. For the mean AoA and AS estimation, our approach presents NRMSEs close to the one developed in [2].
