- Abstract
- This paper introduces the Band Exploration and Channel Sounding System (BECS) as a prototype of 2x8 MIMO wireless channel sounder, which is under developing in ETRI to explore wideband channel and frequency characteristics at 2.6 GHz. Engineering parameters for the BECS implementation are presented and the sounder system response is obtained and analyzed using the hardware channel simulator, Elektrobit PROPsim짰. The impact of imperfect system response on rms delay spread is analyzed using the 3GPP Spatial Channel Model (SCM). Based on Monte-Carlo simulations generating multiple ensembles of the wireless channel, it is found that rms delay spreads measured by the sounder do not depend on the sounder impairment such as the bell-shaped system response induced from RRC filter, and the equalized matched filter technique can improve the delay resolution against the imperfect system response.
