In particular, we propose an iterative algorithm which successively designs the low-resolution analog precoder and combiner pair, aiming at conditionally maximizing the spectral efficiency. Then, the digital precoder and combiner are computed based on the obtained effective baseband channel to further enhance the spectral efficiency. In an effort to achieve an even more hardware-efficient large antenna array, we also investigate the design of hybrid beamformers with one-bit resolution (binary) PSs, and present a novel binary analog precoder and combiner optimization algorithm. After analyzing the computational complexity, the proposed low-resolution hybrid beamforming design is further extended to multiuser MIMO communication systems. Simulation results demonstrate the performance advantages of the proposed algorithms compared to existing low-resolution hybrid beamforming designs, particularly for the one-bit resolution PSs scenario.]]>1222562691149<![CDATA[Spectrum Sharing Backhaul Satellite-Terrestrial Systems via Analog Beamforming]]>1222702811043<![CDATA[A Hardware-Efficient Analog Network Structure for Hybrid Precoding in Millimeter Wave Systems]]>fixed phase shifter (FPS) implementation. It only requires a small number of phase shifters with quantized and fixed phases. To enhance the spectral efficiency, a switch network is put forward to provide dynamic connections from phase shifters to antennas, which is adaptive to the channel states. An effective alternating minimization algorithm is developed with closed-form solutions in each iteration to determine the hybrid precoder and the states of switches. Moreover, to further reduce the hardware complexity, a group-connected mapping strategy is proposed to reduce the number of switches. Simulation results show that the FPS fully-connected hybrid precoder achieves higher hardware efficiency with much fewer phase shifters than existing proposals. Furthermore, the group-connected mapping achieves a good balance between spectral efficiency and hardware complexity.]]>1222822971399<![CDATA[Energy Efficiency of mmWave Massive MIMO Precoding With Low-Resolution DACs]]>1222983121074<![CDATA[Joint Design of Beam Selection and Precoding Matrices for mmWave MU-MIMO Systems Relying on Lens Antenna Arrays]]>1223133251529<![CDATA[Hybrid Beamforming Based on Implicit Channel State Information for Millimeter Wave Links]]>1223263391060<![CDATA[Data-Driven-Based Analog Beam Selection for Hybrid Beamforming Under mm-Wave Channels]]>1223403521048<![CDATA[Channel Estimation and Hybrid Precoding for Frequency Selective Multiuser mmWave MIMO Systems]]>122353367795<![CDATA[Channel-Reconstruction-Based Hybrid Precoding for Millimeter-Wave Multi-User MIMO Systems]]>beam alignment phase. Each user uses a user-specific codebook of beamforming vectors to learn the top-$P$ (where $P geq 1$) beam pairs in terms of the observed signal-to-noise ratio (${text{SNR}}$ ) in a single-user setting. The top-$P$ beam indices along with their ${text{SNR}}$ s are fed back from each user and the base station leverages this information to generate beam weights for simultaneous transmissions. A typical method to generate the beam weights is to use only the best beam for each user and either steer energy along this beam, or to utilize this information to reduce multi-user interference. The other beams are used as fall-back options to address blockage or mobility. Such an approach completely discards information learned about the channel condition(s) even though each user feeds back this information. With this background, this paper develops an advanced directional precoding structure for simultaneous transmissions at the cost of an additional marginal feedback overhead. This construction relies on three main innovations: first, additional feedback to allow the base station to reconstruct a rank- $P$ approximation of the channel matrix between it and each user; se-
ond, a zero-forcing structure that leverages this information to combat multi-user interference by remaining agnostic of the receiver beam knowledge in the precoder design; and third, a hybrid precoding architecture that allows both amplitude and phase control at low complexity and cost to allow the implementation of the zero-forcing structure. Numerical studies show that the proposed scheme results in a significant sum rate performance improvement over naïve schemes even with a coarse initial beam alignment codebook.]]>1223833981286<![CDATA[Programmable Weight Phased-Array Transmission for Secure Millimeter-Wave Wireless Communications]]>$33.0%$.]]>12239941333839
