Deep Reinforcement Learning for Random Access in Machine-Type Communication
Muhammad Awais Jadoon, Adriano Pastore, Monica Navarro +1
Random access (RA) schemes are a topic of high interest in machine-type communication (MTC). In RA protocols, backoff techniques such as exponential backoff (EB) are used to stabil…
Probabilistic MIMO Symbol Detection with Expectation Consistency Approximate Inference
Javier Cépedes, Pablo M. Olmos, Matilde Sánchez-Fernández +1
In this paper we explore low-complexity probabilistic algorithms for soft symbol detection in high-dimensional multiple-input multiple-output (MIMO) systems. We present a novel alg…
Tree-Structure Expectation Propagation for LDPC Decoding over the BEC
Pablo M. Olmos, Juan José Murillo-Fuentes, Fernando Pérez-Cruz
We present the tree-structure expectation propagation (Tree-EP) algorithm to decode low-density parity-check (LDPC) codes over discrete memoryless channels (DMCs). EP generalizes b…
Tree-structure Expectation Propagation for Decoding LDPC codes over Binary Erasure Channels
Pablo M. Olmos, Juan José Murillo-Fuentes
Expectation Propagation is a generalization to Belief Propagation (BP) in two ways. First, it can be used with any exponential family distribution over the cliques in the graph. Se…
Channel Decoding with a Bayesian Equalizer
Luis Salamanca, Juan José Murillo-Fuentes, Fernando Pérez-Cruz
Low-density parity-check (LPDC) decoders assume the channel estate information (CSI) is known and they have the true a posteriori probability (APP) for each transmitted bit. But in…
