Special Issue Information

Dear Colleagues,

Channel estimation (CS) and adaptive modulation (AM) are key physical layer techniques to enhance spectral efficiency over time/frequency/spatial variant channels while maintaining a target error rate.

At present, these tasks have to be performed in communication channels with a large variety of characteristics, which range from channel response sparsity, as in the upcoming fifth-generation (5G) millimeter-wave communications; extremely rapid channel response variations, as in underwater acoustic (UWA) and vehicle-to-everything (V2X) communications; and cyclostationary noise, as in power line communications (PLC), just to mention a few examples.

The diversity of system features and operation modes (e.g., massive MIMO and in-band full-duplex), receiver architectures (e.g., iterative architectures), network configurations (e.g., relay networks), and processing techniques (e.g., machine learning) have also widened the catalogue of CS and AM strategies and methods.

This Special Issue is aimed at collecting high-quality contributions addressing CS and AM problems in all communication scenarios. Hence, possible topics include but are not limited to the following:

  • Decision-directed and pilot-based CS;
  • Compressed-sensing and parametric model-based CS;
  • CS with non-orthogonal pilot signals;
  • CS in single and multicarrier systems;
  • CS in single and multiple input–output systems;
  • Blind CS;
  • Iterative CS;
  • CS and AM using machine learning;
  • CS and AM for optical communication systems;
  • CS and AM for new channel fading models;
  • CS and AM in relay networks;
  • AM, coding, and HARQ;
  • AM and network coding;
  • AM with adaptive threshold;
  • AM using unconventional symbol constellations (hexagonal, hierarchical, etc.);
  • Efficient CSI feedback transmission;
  • Blind recognition of modulation and coding level;
  • AM oriented by QoS requirements;
  • AM performance in cellular networks;
  • AM for cognitive radio systems.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Electronics is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
