To better serve future vehicular network, we judiciously design an anti-Doppler index modulation termed as pre-compensation assisted generalized beam index modulation (PC-GBIM) for wideband mmWave massive multiple-input multiple-output (mMIMO) systems. [1] To account for the propagation delay across the antenna array, which cannot be neglected in wideband mmWave massive MIMO systems, the discrete time channel that models the spatial wideband effect is developed. [2] This paper proposes a novel 3D localization method for wideband mmWave massive MIMO systems. [3] To this end, in this paper, we investigate an energy-efficient hybrid precoding scheme using one-bit PSs for practical frequency-selective wideband mmWave massive MIMO systems.

Hence, we dedicate our efforts to the design of hybrid TPC for wideband mmWave MIMO systems, where the beam squint dramatically affects the system performance. [1] Next a beamspace domain representation of the mmWave MIMO channel is obtained, followed by the development of the sparse-FBLMS (SFBLMS) scheme for the estimation of the wideband mmWave MIMO channel that additionally exploits the angular-sparsity for improved channel estimation performance. [2] Simulation results show remarkable performance gains of the proposed approaches for wideband mmWave MIMO hardware-constrained systems. [3] However, the beamforming gain is actually frequency-dependent in wideband mmWave MIMO systems. [4] In this paper, we propose a phase shifter-aided beam selection network, which enables a single RF chain to support multiple focused-energy beams, for mitigating the beam squint in wideband mmWave MIMO systems. [5]因此，我们致力于为宽带毫米波 MIMO 系统设计混合 TPC，其中波束斜视会显着影响系统性能。 [1] 接下来，获得毫米波 MIMO 信道的波束空间域表示，然后开发用于估计宽带毫米波 MIMO 信道的稀疏 FBLMS (SFBLMS) 方案，该方案还利用角稀疏性来提高信道估计性能。 [2] 仿真结果表明，对于宽带毫米波 MIMO 硬件受限系统，所提出的方法具有显着的性能提升。 [3] 然而，在宽带毫米波 MIMO 系统中，波束赋形增益实际上取决于频率。 [4] 在本文中，我们提出了一种移相器辅助波束选择网络，它使单个射频链能够支持多个聚焦能量波束，以减轻宽带毫米波 MIMO 系统中的波束斜视。 [5]

Accordingly, the channel estimation issue in wideband mmWave system with finite-bit ADCs becomes even challenging. [1] In this paper, we consider studying the sub-connected wideband mmWave system and propose a frequency selective wideband hybrid beamforming technique. [2] Numerical results reveal that for wideband mmWave systems with low-resolution ADCs, the timing synchronization performance of our proposed method outperforms the existing approaches due to the improvement in the received synchronization SQNR. [3]因此，具有有限位 ADC 的宽带毫米波系统中的信道估计问题变得更加具有挑战性。 [1] 在本文中，我们考虑研究子连接宽带毫米波系统，并提出一种频率选择性宽带混合波束成形技术。 [2] 数值结果表明，对于具有低分辨率 ADC 的宽带毫米波系统，由于接收同步 SQNR 的改进，我们提出的方法的定时同步性能优于现有方法。 [3]

In this paper, we develop a joint design of transmit power allocation, beamforming, and receive power splitting for SWIPT downlink systems in wideband mmWave channel. [1] Most existing schemes assume that a wideband mmWave channel exhibits a common sparsity in the frequency domain. [2] Conventionally, for wideband mmWave channels, choosing the precoders/combiners have involved frequency-selective designs that are based on channel state information. [3]在本文中，我们为宽带毫米波信道中的 SWIPT 下行链路系统开发了一种发射功率分配、波束成形和接收功率分离的联合设计。 [1] 大多数现有方案都假设宽带毫米波信道在频域中表现出共同的稀疏性。 [2] 通常，对于宽带毫米波通道，选择预编码器/组合器涉及基于通道状态信息的频率选择设计。 [3]

In this paper, we focus on 28 GHz wideband mmWave signal propagation characteristics at Johnston Regional Airport (JNX), a local airport near Raleigh, NC. [1] Specifically, we analyzed the identification performance of single- valued feature extracted from channel impulse response (CIR), and confirmed that rise-time is an attractive features for identification, particularly precise for wideband mmWave signal. [2]在本文中，我们重点关注约翰斯顿地区机场 (JNX) 的 28 GHz 宽带毫米波信号传播特性，该机场是北卡罗来纳州罗利附近的当地机场。 [1] 具体来说，我们分析了从信道脉冲响应 (CIR) 中提取的单值特征的识别性能，并证实上升时间是一个有吸引力的识别特征，特别是对于宽带毫米波信号而言更精确。 [2]

The above irreconcilable contradiction will dramatically affect the system performance, considering the RIS usually consists of enormous elements and the bandwidth of wideband mmWave communications may be up to several GHz. [1] To address this issue, we design an intelligent reflecting surface (IRS) assisted wideband mmWave communication system with lens antenna array with limited radio frequency (RF) chains. [2]考虑到RIS通常由巨大的元件组成，宽带毫米波通信的带宽可能高达数GHz，上述不可调和的矛盾将极大地影响系统性能。 [1] 为了解决这个问题，我们设计了一种智能反射面 (IRS) 辅助宽带毫米波通信系统，该系统带有带有有限射频 (RF) 链的透镜天线阵列。 [2]
