The key bottleneck in current systems turns out to be the phase noise in the local oscillators in the transmit and receive chain of the full-duplex node. ...
In this paper, we investigate the root cause of performance bottlenecks in current full-duplex systems. ...
Thus, the sum total of digital and active analog cancellation in [2] is limited by phase noise of the local oscillator at the full-duplex node.

Our analysis shows that when phase noise dominates mixer and quantization noise, full-duplex systems can use either active analog cancellation or base-band digital cancellation to achieve near-identical ...
Using the detailed signal model, we study the rate gain region, which is defined as the region of received signal-of-interest strength where full-duplex systems outperform half-duplex systems in terms ...
However, none of the current full-duplex wireless systems gain over half-duplex transmission in all operation regimes, largely due to imperfect self-interference cancellation. ...
