Low-Density Parity-Check Codes and Spatial Coupling for Quantitative Group Testing
Mgeni Makambi Mashauri, Alexandre Graell i Amat, Michael Lentmaier
A non-adaptive quantitative group testing (GT) scheme based on sparse codes-on-graphs in combination with low-complexity peeling decoding was introduced and analyzed by Karimi et a…
Robust Performance Over Changing Intersymbol Interference Channels by Spatial Coupling
Mgeni Makambi Mashauri, Alexandre Graell i Amat, Michael Lentmaier
We show that spatially coupled low-density parity-check (LDPC) codes yield robust performance over changing intersymbol interfere (ISI) channels with optimal and suboptimal detecto…
On the Universality of Spatially Coupled LDPC Codes Over Intersymbol Interference Channels
Mgeni Makambi Mashauri, Alexandre Graell i Amat, Michael Lentmaier
In this paper, we derive the exact input/output transfer functions of the optimal a-posteriori probability channel detector for a general ISI channel with erasures. Considering thr…
Age of Information in Slotted ALOHA With Energy Harvesting
Khac-Hoang Ngo, Giuseppe Durisi, Alexandre Graell i Amat +2
We examine the age of information (AoI) of a status update system that incorporates energy harvesting and uses the slotted ALOHA protocol. We derive analytically the average AoI an…
Impact of Phase Noise on Uplink Cell-Free Massive MIMO OFDM
Yibo Wu, Luca Sanguinetti, Ulf Gustavsson +2
Cell-Free massive MIMO networks provide huge power gains and resolve inter-cell interference by coherent processing over a massive number of distributed instead of co-located anten…
Irregular Repetition Slotted ALOHA Over the Binary Adder Channel
Khac-Hoang Ngo, Alexandre Graell i Amat, Giuseppe Durisi
We propose an irregular repetition slotted ALOHA (IRSA) based random-access protocol for the binary adder channel (BAC). The BAC captures important physical-layer concepts, such as…
