For the mobile radio channel parameter estimation, the Space-Alternating Generalized Expectation-maximization (SAGE) algorithm is a popular scheme to estimate the individual path parameters, i.e., the relative delay, incidence azimuth, Doppler frequency, and complex amplitude of impinging waves. Because of the constraint of bandwidth of channel sounding signal and the limitation of the number of antennas,...
In this contribution, we investigate the applicability of using multiple propagation paths to estimate the temporal auto-correlation function and the coherence time of wireless propagation channels. The Space-Alternating Generalized Expectation-maximization (SAGE) algorithm is applied for extracting the paths from measurement data. It is found that the channel auto-correlation function and coherence...
