MIMO Detection with Spatial Sigma-Delta ADCs: A Variational Bayesian Approach

no code implementations4 Oct 2024 Toan-Van Nguyen, Sajjad Nassirpour, Italo Atzeni, Antti Tolli, A. Lee Swindlehurst, Duy H. N. Nguyen

The effects of the steering angle of the $\Sigma\Delta$ architecture, the number of ADC resolution bits, and the number of antennas and users are also extensively analyzed.

Hybrid Beamforming for mm-Wave Massive MIMO Systems with Partially Connected RF Architecture

no code implementations4 Dec 2020 Mohammad Majidzadeh, Jarkko Kaleva, Nuutti Tervo, Harri Pennanen, Antti Tolli, Matti Latva-aho

Hybrid analog-digital beamforming has been recognised as a promising approach for large-scale MIMO implementations with a reduced number of costly and power-hungry RF chains.

D2D Assisted Multi-antenna Coded Caching

no code implementations9 Oct 2020 Hamidreza Bakhshzad Mahmoodi, Jarkko Kaleva, Seyed Pooya Shariatpanahi, Antti Tolli

We identify scenarios and conditions where D2D transmission can reduce the delivery time.
