Transmission Capacity of Full-Duplex MIMO Ad-Hoc Network with Limited Self-Interference Cancellation
In this paper, we propose a joint transceiver beamforming design to
simultaneously mitigate self-interference (SI) and partial inter-node
interference for full-duplex multiple-input and multiple-output ad-hoc network,
and then derive the transmission capacity upper bound (TC-UB) for the
corresponding network. Condition on a specified transceiver antenna's
configuration, we allow the SI effect to be cancelled at transmitter side, and
offer an additional degree-of-freedom at receiver side for more inter-node
interference cancellation. In addition, due to the proposed beamforming design
and imperfect SI channel estimation, the conventional method to obtain the
TC-UB is not applicable. This motivates us to exploit the dominating interferer
region plus Newton-Raphson method to iteratively formulate the TC-UB. The
results show that the derived TC-UB is quite close to the actual one especially
when the number of receive-antenna is small. Moreover, our proposed beamforming
design outperforms the existing beamforming strategies, and FD mode works
better than HD mode in low signal-to-noise ratio region.Comment: 7 pages, 4 figures, accepted by Globecom 201
