“…It was shown that this PN can result in deceptive channel capacity increase up to 100% [4]. In related studies the impact of PN on direction of arrival estimation was investigated in [7] for single-input-multiple-output (SIMO) Manuscript systems. In context of single antenna transmission schemes, the impact of measurement impairments was studied in [8].…”

“…The worst case scenario in terms of channel capacity estimation accuracy happens when the physical channel matrix is a rank one matrix, , and the presence of PN results in a full-rank effective channel matrix, . Under this scenario the error in the ergodic channel capacity can be written as (7) In a high SNR scenario, (7) can be approximated as (8) The maximum effect of PN on the rank one physical channel matrix is to convert it to a diagonal matrix with equal eigenvalues each with power gain of . For a MIMO system with equal number of transmit and receive antennas, , the power gain of each eigenvalue is just the total power in the channel matrix divided by the MIMO system size, i.e., , .…”

“…Kivinen et al [8] investigated the impact of free-running oscillator PN effect on Fourier-based direction of arrival (DOA) estimation for single-input multiple-output (SIMO) systems. A recent contribution, [9], investigates the impact of PN in phase-locked LOs on the capacity of fully correlated rank-one channels as well as full rank channels.…”

“…In contrast to [8], we study the impact of the PN on the MPC parameters obtained by the high-resolution SAGE algorithm [10], which has become the de-facto standard for the evaluation of double-directional measurement campaigns. In contrast to [9], we investigate the impact of free-running oscillators on the capacity.…”
