“…Consequently, mmWave channels are relevant to the geometry of antenna arrays. With half-spaced ULAs adopted at the transmitter and receiver, the channel matrix can be expressed as [19], [26], [27], [29], [33], [34] …”

“…However, the overall search time is prohibitive, because the number of candidate beam directions is usually large for mmWave communication. To improve the search efficiency, a hierarchy of codebooks may be defined [3], [17], [18], [25]- [27]. For example, a coarse codebook may be defined with a small number of coarse/low-resolution beams (or sectors) covering the intended angle range, while a fine codebook may be defined with a large number of fine/highresolution beams covering the same intended angle range, and that a coarse beam may have the same/similar coverage as that of multiple fine beams together.…”

“…In [19], the hybrid precoding structure was adopted to shape wider beams by exploiting the sparse reconstruction approach, but high-quality wide beams can be shaped only when the number of RF chains is large enough and deep sinks within the angle range appear otherwise. In [27], a binary-tree structured hierarchical codebook was designed by using antenna deactivation, where wider beams were generated by turning off part of the antennas. A complete codebook was designed with closed-form expressions provided therein.…”

“…Closedform expressions are provided to generate the codebook. In the proposed approach, the beams of the sub-arrays steer towards widely-gapped directions to broaden beams, which is essentially different from [26], and the deactivation operates on the sub-arrays instead of individual antennas like that in [27]. To the best of our knowledge, this is the first to propose these two criteria and the joint sub-array and deactivation codebook design.…”

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.
