Automatic Regularization for Linear MMSE Filters
Daniel Gomes de Pinho Zanco, Leszek Szczecinski, Jacob Benesty
In this work, we consider the problem of regularization in the design of minimum mean square error (MMSE) linear filters. Using the relationship with statistical machine learning m…
Parametric Phase Tracking via Expectation Propagation
Leszek Szczecinski, Hsan Bouazizi, Ahikam Aharony
In this work we propose simple algorithms for signal detection in a single-carrier transmission corrupted by a strong phase noise. The proposed phase tracking algorithms are formul…
AMC and HARQ: How to Increase the Throughput
Mohammed Jabi, Leszek Szczecinski, Mustapha Benjillali +2
In this work, we consider transmissions over block fading channels and assume that adaptive modulation and coding (AMC) and hybrid automatic repeat request (HARQ) are implemented.…

HARQ and AMC: Friends or Foes?
Redouane Sassioui, Mohammed Jabi, Leszek Szczecinski +3
To ensure reliable communication in randomly varying and error-prone channels, wireless systems use adaptive modulation and coding (AMC) as well as hybrid ARQ (HARQ). In order to e…

Mohammed Jabi, Aata El Hamss, Leszek Szczecinski +1
In this work we consider incremental redundancy (IR) hybrid automatic repeat request (HARQ), where transmission rounds are carried out over independent block-fading channels. We pr…
Opportunistic Relaying without CSI: Optimizing Variable-Rate HARQ
Saeed R. Khosravirad, Leszek Szczecinski, Fabrice Labeau
We analyze the opportunistic relaying based on HARQ transmission over the block-fading channel with absence of channel state information (CSI) at the transmitter nodes. We assume t…
Outage Minimization via Power Adaptation and Allocation for Truncated Hybrid ARQ
Mohammed Jabi, Leszek Szczecinski, Mustapha Benjillali +1
