Full- or half-duplex? A capacity analysis with bounded radio resources

Exploring full-duplex gains in multi-cell wireless networks: A spatial stochastic framework

“…Existing analysis mostly assumes half-duplex radios, and targets capacity scaling laws under an asymptotically growing node population. Information theoretic properties of single-cell full-duplex WLAN are analyzed recently [27]. Yet it remains an open problem what is the fundamental gain when full-duplex interplays with multi-cell interference and spatial reuse.…”

Sum-rate performance and impact of self-interference cancellation on full-duplex wireless systems

“…Moreover, there is a growing interest within industry and academia for the design and implementation of FD point-to-point single-antenna [1], [2] and multi-antenna [4], [5], FD relay [6]- [8], and FD multiuser systems [9]. In FD systems, the self-interference generated by own transmissions is progressively canceled in multiple stages so that simultaneous reception is possible [1]- [3].…”

“…After performing the best possible cancellation, the residual of the self-interference limits the expected bene ts of FD. For the purpose of theoretical studies, several residual self-interference models have been proposed [2], [4], [5], [7], [8]. Particularly, in [2], [4], the residual self-interference is assumed to be noise-like and constant power regardless of the power of the self-interfering signal (i.e., own transmission).…”

Moreover, references [5], [7], [8] assume that the residual self-interference is caused by the self-interfering channel estimation error and therefore, the interference power is proportional to the instantaneous transmitted power.…”

“…To answer this question under boundedradio resources (i.e., with a constraint on hardware resources), the ergodic capacity of FD system is analyzed in [4] assuming residual self-interference power to be a constant. Moreover, the sum-rate performance of point-to-point multi-antenna system under a short-term power constraint is analyzed in [5] with an emphasis on the effects of transceiver limited dynamic range.…”
