Hybrid Beamforming for Bidirectional Massive MIMO Full Duplex Under Practical Considerations

Dirk Slock

Résumé

In-band Full-Duplex (FD) is a promising wireless transmission technology allowing to increase data rates by up to a factor of two, via simultaneous transmission and reception, but with a potential to increase system throughput even much more in cognitive radio and random access systems thanks to simultaneous transmission and sensing. In this work, we consider a practical hybrid beamforming design for a bidirectional massive MIMO FD system under the joint per-antenna and sum-power constraints. Moreover, we consider non-ideal circuitry in the transmit and receive chains, which is modelled with the limited dynamic range (LDR) noise model. The per-antenna power constraints take into account the actual physical limits of the power amplifiers and the sum-power constraints are imposed to limit the total transmit power. The precoders are optimized with alternating optimization by using the minorization-maximization approach. Simulation results show significant performance improvement compared to a traditional bidirectional half-duplex system.
