Center node: "transmission capacity of full duplex mimo ad hoc network with limited self interference cancellation"
  Abstract: In this paper, we propose a joint transceiver beamforming design to mitigate self-interference and inter-node interference simultaneously for full-duplex multiple-input and multiple-output ad-hoc network, and derive the transmission capacity upper bound (TC-UB) for the considered network. Condition on a specified transceiver antenna's configuration, we allow the self-interference 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 imperfect self-interference channel estimation, the derivation of TC-UB needs to take the channel estimation error into account. In this case, the conventional method to obtain the TC-UB is not applicable. This motivates us to exploit the dominating interferer region and then utilize 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.
