Estimation of the Radio Channel Parameters From a Circular Array With Directional Antennas

Free registration required

Executive Summary

Channel sounding, channel modeling and their parameter extraction in particular considering MIMO configurations, plays an important role for today's realistic wireless system design and evaluation. The analysis of the gathered channel sounding data has to match the specifics in the measurement system configuration. Within this contribution directional antenna arrays are used at both sides of the measured link. Furthermore, the measurement system applies automatic gain control between subsequent MIMO snapshots and additionally within the MIMO matrix. Both features lead to improved measurement accuracy. A new extension of existing power and delay domain analysis procedures considering the automatic gain control within the MIMO matrix is introduced and evaluated.
