EVM Mitigation with PAPR and ACLR Constraints in Large-Scale MIMO-OFDM Using TOP-ADMM
Shashi Kant, Mats Bengtsson, Gabor Fodor +2
Although signal distortion-based peak-to-average power ratio (PAPR) reduction is a feasible candidate for orthogonal frequency division multiplexing (OFDM) to meet standard/regulat…
A Learning-Based Approach to Address Complexity-Reliability Tradeoff in OS Decoders
Baptiste Cavarec, Hasan Basri Celebi, Mats Bengtsson +1
In this paper, we study the tradeoffs between complexity and reliability for decoding large linear block codes. We show that using artificial neural networks to predict the require…
EVM-Constrained and Mask-Compliant MIMO-OFDM Spectral Precoding
Shashi Kant, Mats Bengtsson, Gabor Fodor +2
Spectral precoding is a promising technique to suppress out-of-band emissions and comply with leakage constraints over adjacent frequency channels and with mask requirements on the…
Deep unfolding of the weighted MMSE beamforming algorithm
Lissy Pellaco, Mats Bengtsson, Joakim Jaldén
Downlink beamforming is a key technology for cellular networks. However, computing the transmit beamformer that maximizes the weighted sum rate subject to a power constraint is an…
Low-Complexity OFDM Spectral Precoding
Shashi Kant, Gabor Fodor, Mats Bengtsson +2
This paper proposes a new large-scale mask-compliant spectral precoder (LS-MSP) for orthogonal frequency division multiplexing systems. In this paper, we first consider a previousl…
On the Energy Efficiency of MIMO Hybrid Beamforming for Millimeter Wave Systems with Nonlinear Power Amplifiers
Nima N. Moghadam, Gábor Fodor, Mats Bengtsson +1
Multiple-input multiple-output (MIMO) millimeter wave (mmWave) systems are vulnerable to hardware impairments due to operating at high frequencies and employing a large number of r…
