Summary:Research on millimeter-wave (mmWave) massive multiple-input multiple-output (MIMO) has received much attention. However, due to the propagation characteristics of mmWave, signals will suffer from a significant loss over long range transmission. The mmWave MIMO system may face the challenge of the near-far problem where the user tries to retrieve the information signal (IS) from the base station under the strong intended jamming signal (JS). This letter proposes a novel hybrid beamforming design to cancel the JS that significantly reduces the computational complexity and incurs less feedback signaling overhead. Simulation results demonstrate that our proposed scheme can significantly suppress the interference from the JS and achieve the array gain in the system.
