In this paper we present the architecture of the sounder and demonstrate its performance from back to back tests and from measurements of rms delay spread, path loss and MIMO capacity in an indoor and an outdoor environment. For 20 dB threshold, the rms delay spread for 90% of the measured locations is estimated at 1.4 ns and 1 ns for the indoor and outdoor environments, respectively. MIMO capacity close to the iid channel capacity for 2 by 2 configuration is achieved in both environments.

“…The Cramér-Rao lower bounds (CRLB) and algorithms for estimation of phase noise in single-input single-output (SISO) systems are extensively and thoroughly analyzed in [3], [16]- [30]. However, these results are not applicable to MIMO systems, where a received signal may be affected by multiple phase noise parameters that need to be jointly estimated at the receiver [13], [31]- [33]. As a matter of fact, for SISO systems, Kalman filterbased methods have been effectively applied in [16], [20], [25], [29] for signal detection in the presence of phase noise.…”

“…The eaffect of phase noise on the capacity and performance of space division multiplexing (SDM) MIMO communication systems has been analyzed in [31]- [33], where it is demonstrated that phase noise can greatly limit the performance of multiantenna systems. In [31], the effect of oscillator configuration at the transceiver antennas and the resulting phase noise on a MIMO beamforming system is analyzed in detail.…”

The large majority of commercially available multiple-input multiple-output (MIMO) radio channel measurement devices (sounders) is based on time-division multiplexed switching (TDMS) of a single transmit/receive radio frequency chain into the elements of a transmit/receive antenna array. While being cost-effective, such a solution can cause significant measurement errors due to phase noise and frequency offset in the local oscillators. In this paper, we systematically analyze the resulting errors and show that, in practice, overestimation of channel capacity by several hundred percent can occur. Overestimation is caused by phase noise (and to a lesser extent frequency offset) leading to an increase of the MIMO channel rank. Our analysis furthermore reveals that the impact of phase errors is, in general, most pronounced if the physical channel has low rank (typical for line-of-sight or poor scattering scenarios).The extreme case of a rank-1 physical channel is analyzed in detail. Finally, we present measurement results obtained from a commercially employed TDMS-based MIMO channel sounder. In the light of the findings of this paper, the results obtained through MIMO channel measurement campaigns using TDMS-based channel sounders should be interpreted with great care.
