“…On Closed-loop IEEE 802. 16-2004 WiMAX The potential performance of WiMAX has been evaluated in a multitude of simulations, for example [28][29][30][31][32][33][34][35][36][37]. In contrast to [28][29][30][31][32][33][34][35][36], only [37] presents the results in terms of throughput for a system with link adaptation, but limited to the SISO case.…”

The impact of transmit-antenna spacing and signal-to-noiseratio on channel capacity has been measured intensively in a variety of scenarios. When looking at the physical layer throughput of a multiantenna communication system, the behavior over antenna spacing may look completely different, leading to other conclusions regarding the optimal antenna distance.In this paper, we compare -by testbed measurements-the closedloop throughput of a standard compliant 2×2 IEEE 802.16-2004 WiMAX radio link with the unconstrained capacity and the mutual information of the channel. Results are presented for base-station antenna spacings of 0 wavelengths (cross polarization) as well as spacings between 0.6 wavelengths and 7.7 wavelengths (equal polarization).

Abstract-In this work, we present physical layer throughput measurement results of a WiMAX link implemented according to IEEE 802.16-2004. The measurements were carried out in an alpine and an urban scenario using the Vienna MIMO Testbed. We compare the measured throughput to three different theoretical bounds: 1) the channel capacity, 2) the mutual information, and 3) a so-called "achievable throughput" which takes inherent system losses into account. Furthermore, the impact of different channel codes and channel estimators on the measured throughput is analyzed.
