Robust Beamforming in Interference Channels with Imperfect Transmitter Channel Information
We consider K links operating concurrently in the same spectral band. Each transmitter has multiple antennas, while each receiver uses a single antenna. This setting corresponds to the multiple-input single-output interference channel. We assume perfect channel state information at the receivers whereas the transmitters only have estimates of the true channels. The channel estimation errors are...
متن کاملBeamforming design with proactive interference cancelation in MISO interference channels
In this paper, we design coordinated beamforming at base stations (BSs) to facilitate interference cancelation at users in interference networks, where each BS is equipped with multiple antennas and each user is with a single antenna. By assuming that each user can select the best decoding strategy to mitigate the interference, either canceling the interference after decoding when it is strong ...
متن کاملA Probabilistic Constraint Approach for Robust Beamforming with Imperfect Channel Information
Transmit beamforming is a powerful technique for enhancing performance of wireless communication systems. Most existing transmit beamforming techniques require perfect channel state information at the transmitter (CSIT), which is typically not available in practice. In such situations, the design should take errors in CSIT into account to avoid performance degradation. Among two popular robust ...
متن کاملDistributed Queue-Aware Beamforming in MISO Interference Channels
We study distributed queue-aware beamforming in a multiple input single output (MISO) interference channel. Instead of assuming full buffer traffic, we adopt a more realistic traffic model where the data arrival rates are finite, and the beamformers are adaptive to the data in the buffer. We propose a simple dynamic beamforming strategy which significantly improves the average sum rate compared...
متن کاملRobust Downlink Beamforming for Multiuser MISO SWIPT Systems ⋆
In this paper, we studies robust downlink beamforming for a multiuser multiple-input single-output (MISO) simultaneous wireless information and power transfer (SWIPT) system when only imperfect knowledge of the channel state information (CSI) is available at the transmitter. Specifically, we exploit two different models to describe CSI errors: a) deterministic bounded and b) stochastic random. ...
