摘要

本文给出了波束形成全双工系统中反射自干扰信道测量的结果和分析。为了测量毫米波波段反射自干扰信道，我们使用中心频率为27.925GHz的收发器发送信噪比大于100 dB的18位PN序列信号。在测量结果中，我们发现由于附近各种物体的反射导致的自干扰信道具有较长的传播延迟。由于传统的模拟对消电路具有有限的模拟延迟，因此无法消除这种自干扰信道。为了克服这一限制，采用机会全双工方案和考虑残余自干扰的波束选择方法似乎是一个很好的解决方案。

Reflected Self-Interference Channel Measurement for mmWave Beamformed Full-Duplex System

In this paper, we present the results and analyses of the reflected self-interference channel measurement in the beamformed full-duplex system. To measure the reflected self-interference channel in mmWave band, we transmit 18-bit PN sequence signal with more than 100 dB SNR using a transceiver with 27.925GHz center frequency. In the measurement results, we found the self-interference channel with long propagation delay caused by the reflection due to various nearby objects. This self-interference channel cannot be removed using conventional analog cancellation circuit which has limited analog delay. To overcome this limitation, it seems to be a good solution to apply opportunistic full-duplex scheme and a beam selection approach taking into account the residual self-interference.
