Determining the Number of Propagation Paths from Broadband Mimo Measurements via Bootstrapped Likelihoods and the False Discovery Rate Criterion - Part II: Application

Abstract

In this contribution, we apply a multiple hypothesis test procedure to real broadband MIMO antenna array measurements recorded with a RUSK-ATM vector channel sounder. The RUSK-ATM vector channel sounder operated at a center frequency of 2 GHz and a bandwidth of 120 MHz. Maximum-likelihood estimates for propagation delay, direction of arrival, direction of departure are obtained with the space alternating generalized expectation-maximization (SAGE) algorithm. The Benjamini-Hochberg procedure is invoked using the bootstrap approximation to select the number of propagation paths for a given false discovery rate.
