A Dynamic Clustering and Resource Allocation Algorithm for Downlink CoMP Systems with Multiple Antenna UEs
Paolo Baracca, Federico Boccardi, Nevio Benvenuto
Coordinated multi-point (CoMP) schemes have been widely studied in the recent years to tackle the inter-cell interference. In practice, latency and throughput constraints on the ba…
Massive MU-MIMO Downlink TDD Systems with Linear Precoding and Downlink Pilots
Hien Quoc Ngo, Erik G. Larsson, Thomas L. Marzetta
We consider a massive MU-MIMO downlink time-division duplex system where a base station (BS) equipped with many antennas serves several single-antenna users in the same time-freque…
Designing Multi-User MIMO for Energy Efficiency: When is Massive MIMO the Answer?
Emil Björnson, Luca Sanguinetti, Jakob Hoydis +1
Assume that a multi-user multiple-input multiple-output (MIMO) communication system must be designed to cover a given area with maximal energy efficiency (bit/Joule). What are the…
On the Convergence Speed of Spatially Coupled LDPC Ensembles
Vahid Aref, Laurent Schmalen, Stephan ten Brink
Spatially coupled low-density parity-check codes show an outstanding performance under the low-complexity belief propagation (BP) decoding algorithm. They exhibit a peculiar conver…
Approaching the Rate-Distortion Limit with Spatial Coupling, Belief propagation and Decimation
Vahid Aref, Nicolas Macris, Marc Vuffray
We investigate an encoding scheme for lossy compression of a binary symmetric source based on simple spatially coupled Low-Density Generator-Matrix codes. The degree of the check n…
Massive MIMO Systems with Non-Ideal Hardware: Energy Efficiency, Estimation, and Capacity Limits
Emil Björnson, Jakob Hoydis, Marios Kountouris +1
The use of large-scale antenna arrays can bring substantial improvements in energy and/or spectral efficiency to wireless systems due to the greatly improved spatial resolution and…
