Special Issue Information

Dear Colleagues,

To meet the rising demand for high-speed data services, wireless networks must exploit the available frequency spectrum more efficiently. One key limit to spectrum utilization efficiency involves the current practice of half-duplex communication, in which a node either transmits or receives a signal in a single-channel usage. This separation prevents self-interference, which has frequently been seen as an insurmountable technical problem. Promoted by the popularity of small-cell wireless systems, recent works have provided experimental evidence and methodologies for full-duplex communication, in which a node transmits and receives signals at the same time and on the same frequency band. Full-duplex communications have the potential to improve the attainable spectral efficiency and throughput and reduce latency.

This Special Issue will provide a synthesized source of recent research results and to serve as a springboard for future work in Full-Duplex Wireless Communications. The possible topics include, but are not limited to the following:

  • Advanced self-interference cancellation techniques for full-duplex
  • Advanced antenna and transceiver designs for full-duplex
  • Full-duplex reconfigurable intelligent (meta)surfaces
  • Full-duplex techniques with wireless power and energy harvesting
  • Full-duplex for simultaneous communication and sensing
  • Full-duplex millimeter-wave/THz systems
  • Multiple input multiple output full-duplex transceiver design
  • Performance analysis of full-duplex transceivers, systems, and networks
  • Physical layer security and full-duplex techniques
  • Resource allocation and user scheduling in full-duplex networks
  • Stochastic geometry for full-duplex systems
  • Experimental evaluation of full-duplex transceivers and networks

The paper proposes a joint semi-blind algorithm for simultaneously cancelling the self-interference component and estimating the propagation channel in 5G Quasi-Cyclic Low-Density Parity-Check (QC-LDPC)-encoded short-packet Full-Duplex (FD) transmissions. To avoid the effect of channel estimation processes when using short-packet transmissions, this semi-blind algorithm was developed by taking into account only a small number (four at least) pilot symbols, which was integrated with the intended information sequence and used for the feedback loop of the estimation of the channels. The results showed that this semi-blind algorithm not only achieved nearly optimal performance, but also significantly reduced the processing time and computational complexity. This semi-blind algorithm can also improve the performances of the Mean-Squared Error (MSE) and Bit Error Rate (BER). The results of this study highlight the potential efficiency of this joint semi-blind iterative algorithm for 5G and Beyond and/or practical IoT transmission scenarios. Full article

Self-interference occurs when there is electromagnetic coupling between the transmission and reception of the same node; thus, degrading the RX sensitivity to incoming signals. In this paper we present a low-complexity technique for self-interference cancellation in multiple carrier multiple access systems employing whole band direct to digital sampling. In this scenario, multiple users are simultaneously received and transmitted by the system at overlapping arbitrary bandwidths and powers. Traditional algorithms for self-interference mitigation based on recursive least squares (RLS) or least mean squares (LMS), fail to provide sufficient rejection, since the incoming signal is far from being spectrally flat, which is critical for their performance. The proposed algorithm mitigates the interference by modeling the incoming multiple user signal as an autoregressive (AR) process and jointly estimates the AR parameters and self-interference. The resulting algorithm can be implemented using a low-complexity architecture comprised of only two RLS modules. The novel algorithm further satisfies low latency constraints and is adaptive, supporting time varying channel conditions. We compare this to many self-interference cancellation algorithms, mostly adopted from the acoustic echo cancellation literature, and show significant performance gain. Full article
