EMOS Platform: Real-Time Capacity Estimation of MIMO Channels in the UMTS-TDD Band
Résumé
This work presents some initial results concerning the MIMO channel capacity of real wireless channels in the UMTS-TDD band using the Eurecom MIMO Openair Sounder (EMOS). This paper describes the necessary steps to estimate in real-time the wireless MIMO environment, offering the possibility to identify reliable MIMO channels as well as instantaneous channel capacity. In particular, the problems related to additive and phase-shift noise are solved by employing OFDMA technology. Finally, based on measurements, we analyze the impact of polarization on the capacity performance.
