Joint Iterative Blind Self-Interference Cancellation, Propagation Channel Estimation and Decoding Processes in Full-Duplex Transmissions

The paper proposes a joint blind iterative Self-Interference (SI) cancellation, propagation channel estimation and decoding algorithm in Full-Duplex (FD) transmissions via feedback of estimates decoded messages combined with the process Digital Cancellation (DSIC). Different from conventional algorithm, proposed simultaneously self-interference channels decodes each iteration 5G Quasi-Cyclic Low Density Parity Check (QC-LDPC) codes. temporary estimate message are fed back to improve cancellation also as well next iteration. results show that outperforms especially at high signal noise ratio (SNR) small number symbols, requires much less processing time computational complexity while achieving convergence performance. is sensitive SI level than algorithm. further partial scheme, which only use few symbols for estimation, significantly reduce maintaining These good properties seem quite suitable this short-length packet FD Internet-of-Things (IoT) applications green communications.
