title = "Codebook design for millimeter-wave channel estimation with hybrid precoding structure",
abstract = "In this paper, we study hierarchical codebook design for channel estimation in millimeter-wave (mmWave) communications with a hybrid precoding structure. We propose an approach to design a hierarchical codebook exploiting BeaM Widening with Multi-RF-chain Sub-array technique (BMW-MS). To obtain crucial parameters of BMW-MS, we provide a closed-form (CF) solution to pursue a flat beam pattern. Performance comparisons show that BMW-MS/CF outperforms the existing alternatives under the per-antenna power constraint, which is adopted due to the limited saturation power of mmWave power amplifier.",
