Abstract:
This project proposes a joint transceiver beamforming design method for hybrid full-duplex (FD) and half-duplex (HD) ad-hoc networks to cancel co-channel interference and improve system spectral efficiency.
Using a stochastic geometry model, we derive a transmission capacity upper bound (TC-UB) and its two compact versions to characterize network performance. The proposed beamforming design and hybrid-duplex consideration preclude exact TC and conventional methods for TC-UBs.
We use the UB of the largest eigenvalue of desired signals, Alzer’s inequality for the incomplete gamma function, and dominating interference region to formulate one general TC-UB and two compact versions.
Numerical results show that the proposed beamforming method outperforms existing beamforming strategies in exact TC, especially when the number of transmit antennas is greater than the number of receiver antennas per node pair.
The derived general TC-UB can perform similarly to the exact ones, and its two compact versions can at least perform order-wise. We also find break-even points where FD outperforms HD with different system configurations.
