该论文提出一种支持超过20MHz带宽的可重构接收机,通过射频、模拟/混合信号和数字域的自干扰消除(SIC)技术,解决传统的SIC带宽受限(仅几MHz)问题,实现同信道全双工(SC-FD)通信,达到所需的>100dB自干扰抑制。
which limit form factor. Widely-tunable low-noise RF active self-interference cancellation (SIC) (e.g. [1]) is a step towards enabling duplexers with reduced TX/RX isolation as well as adjacent-channel full duplex. However, SIC bandwidth (BW) is limited to a few MHz due to the selectivity of the high-Q duplexer isolation. Recent works suggest that same-channel full duplex (SC-FD) can greatly improve network performance [2-4]. SIC must be pursued in RF, analog/mixedsignal and digital for SC-FD to achieve the >100dB of SIC required, as filtering the SI is not an option. However, SC-FD self-interference channels can be frequency-selective due to ambient reflections [3], requiring silicon-averse bulky delay lines to replicate the delays in the RF SIC path [2].
