“…Instead, analog beamforming is usually preferred, where all the antennas share a single RF chain and have constantamplitude (CA) constraint on their weights [4], [6], [17], [18]. Meanwhile, a hybrid analog/digital precoding structure was also proposed to realize multi-stream/multi-user transmission [9], [12], [13], where a small number of RF chains are tied to a large antenna array.…”

Abstract-In millimeter-wave communication, large antenna arrays are required to achieve high power gain by steering towards each other with narrow beams, which poses the problem to efficiently search the best beam direction in the angle domain at both Tx and Rx sides. As the exhaustive search is time consuming, hierarchical search has been widely accepted to reduce the complexity, and its performance is highly dependent on the codebook design. In this paper, we propose two basic criteria for the hierarchical codebook design, and devise an efficient hierarchical codebook by jointly exploiting sub-array and deactivation (turning-off) antenna processing techniques, where closed-form expressions are provided to generate the codebook. Performance evaluations are conducted under different system and channel models. Results show superiority of the proposed codebook over the existing alternatives.Index Terms-Millimeter wave communication, mmWave, beamforming, codebook design, hierarchial search.

Abstract. Codebook design is a key point in beam-forming which is necessary for millimeter Wave (mmWave) communications to compensate its huge path loss. In our study, we demonstrate the benefits of the number of antenna elements for beamforming; we focus on the number of required beams to cover the whole circle with considering the available number of antenna elements. In addition to, we propose a new codebook structure based on unique phase states. Based on the Array Factor (AF) and Signalto-Noise Ratio (SNR), the proposed codebook is compared and evaluated with the uniform weighting codebook, circular array codebook, and IEEE802.15.3c standard codebook. The results show that the proposed codebook achieves SNR values and side-lobes cancel a bit better than IEEE802.15.3c, but higher peak and wider dynamic range of SNR and better array directivity compared with the uniform weighting and circular antenna codebooks. Thus, the proposed codebook is expected to improve signal quality and increases user throughput significantly.
