Full-duplex channel measurement and analysis based on high dynamic channel sounding system

The full duplex channel, which describes the reflection interference signals in full duplex system, needs to be measured to achieve more precision SIC for full duplex system. Full duplex channel includes both strong leakage interference and weak reflection interference signals, which requires very high dynamic range in channel measurement. In this paper, we designed a high dynamic channel sounding system for the full duplex channel measurement which can provide above 60dB measurement dynamic range, we also performed outdoor full duplex channel measurement at 2.6GHz based on the proposed channel sounding system. The full duplex channel parameters distribution analysis was also performed based on the channel measurement results.
