Abstract
The eigen-beamforming with the end-fire arrangement has been proposed as an interference suppression method suitable for multiple-input multiple-output (MIMO) full-duplex. We clarify the effectiveness of this scheme by experimentally evaluating the bit-error-rate (BER) performance of the uplink desired signal from the mobile terminal while the self-interference in the base station is suppressed. The results showed that the proposed method suppressed interference power by 23.8 dB and achieved BER of 10 −2 even though the desired signal power was 15 dB lower than that of the scenario without the self-interference suppression.
