Symbol Detection with Deep Learning

open access: yesInternational Journal of Advanced Natural Sciences and Engineering Researches, 2023
This study shows the feasibility of detecting some symbols from a distance. Therefore, it will be possible to use these symbols as identification of things, e.g. people, vehicles, objects, information labels etc. There is such a necessity especially for construction sites to know the rough location of workers.

Learning for Detection: MIMO-OFDM Symbol Detection Through Downlink Pilots [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2020
Reservoir computing (RC) is a special recurrent neural network which consists of a fixed high dimensional feature mapping and trained readout weights. In this paper, we introduce a new RC structure for multiple-input, multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) symbol detection, namely windowed echo state network (WESN).

On Multi-User Deep-Learning-Based Non-Coherent DPSK Multiple-Symbol Differential Detection in Massive MIMO Systems

open access: yesIEEE Access, 2021
In view of reducing the complexity of signal detection in massive multiple-input multiple-output (MIMO) receivers, the use of non-coherent detection is favored over usual coherent techniques that require complex channel estimation.

Low-Complexity Near-Optimum Symbol Detection Based on Neural Enhancement of Factor Graphs [PDF]

open access: yesIEEE Transactions on Communications, 2022
We consider the application of the factor graph framework for symbol detection on linear inter-symbol interference channels. Based on the Ungerboeck observation model, a detection algorithm with appealing complexity properties can be derived.

Optimal Sequence Detection and Optimal Symbol-by-Symbol Detection: Similar Algorithms [PDF]

open access: yesIEEE Transactions on Communications, 1982
An algorithm is derived which performs optimal symbol-by-symbol detection of a pulse amplitude modulated sequence. The algorithm is similar to the Viterbi algorithm with the optimality criterion optimal symbol detection rather than optimal sequence detection.

Neural Enhancement of Factor Graph-based Symbol Detection [PDF]

open access: yesInternational Workshop on Signal Processing Advances in Wireless Communications, 2022
We study the application of the factor graph framework for symbol detection on linear inter-symbol interference channels. Cyclic factor graphs have the potential to yield low-complexity symbol detectors, but are suboptimal if the ubiquitous sum-product ...
