Pricing-based Distributed Energy-Efficient Beamforming for MISO Interference Channels
Pan Cunhua, Xu Wei, Wang Jiangzhou +4
In this paper, we consider the problem of maximizing the weighted sum energy efficiency (WS-EE) for multi-input single-output (MISO) interference channels (ICs) which is well ackno…
Joint User Association and Interference Mitigation for D2D-Enabled Heterogeneous Cellular Networks
Tianqing Zhou, Yongming Huang, Luxi Yang
The heterogeneous cellular networks (HCNs) with device-to-device (D2D) communications have been a promising solution to cost-efficient delivery of high data rates. A key challenge…
Uplink Achievable Rate for Massive MIMO with Low-Resolution ADC
Li Fan, Shi Jin, Chao-Kai Wen +1
In this letter, we derive an approximate analytical expression for the uplink achievable rate of a massive multi-input multi-output (MIMO) antenna system when finite precision anal…
Generalized Turbo Signal Recovery for Nonlinear Measurements and Orthogonal Sensing Matrices
Ting Liu, Chao-Kai Wen, Shi Jin +1
In this study, we propose a generalized turbo signal recovery algorithm to estimate a signal from quantized measurements, in which the sensing matrix is a row-orthogonal matrix, su…
Deploying Multiple Antennas on High-speed Trains: Equidistant Strategy v.s. Fixed-Interval Strategy
Yang Lu, Ke Xiong, Pingyi Fan +1
Deploying multiple antennas on high speed trains is an effective way to enhance the information transmission performance for high speed railway (HSR) wireless communication systems…
Channel Acquisition for Massive MIMO-OFDM with Adjustable Phase Shift Pilots
Li You, Xiqi Gao, A. Lee Swindlehurst +1
We propose adjustable phase shift pilots (APSPs) for channel acquisition in wideband massive multiple-input multiple-output (MIMO) systems employing orthogonal frequency division m…
