Special Issue Information
Dear Colleagues,
MU-MIMO, which stands for multi-user multiple-input multiple-output, is a wireless technology in which a base station or wireless router simultaneously serves a group of users or wireless terminals, each with one or more antennas. In contrast, in single-user MIMO (SU-MIMO) technology, only a single multi-antenna receiver is served in a time-frequency resource. MU-MIMO is the key enabler of the recent wireless standards such as 5G new radio (NR) and IEEE 802.11ax. The number of connected wireless terminals and data demands are projected to grow by 30% to 40% annually, which could result in a two- to three-fold increase in the next couple of years. Although adding new frequency bands seems to be a cost-efficient way to meet this demand, there is very limited sub-6 GHz spectrum available. MU-MIMO, in conjunction with massive MIMO, can make more efficient use of this spectrum and improve system capacity. This Special Issue focuses on the analysis, design, and implementation of MU-MIMO systems. Topics of interest include but are not limited to the following:
- MU-MIMO for 5G sub-6 GHz and mmWave networks;
- Scheduling for MU-MIMO systems;
- Cooperative and multi-cell MU-MIMO;
- MU-MIMO using hybrid massive MIMO architecture;
- MU-MIMO for FDD systems with quantized CSI;
- MU-MIMO algorithms complexity and performance tradeoff;
- Hardware impairments in MU-MIMO systems;
- MU-MIMO experimental measurements and trial results.

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 submissions that pass pre-check are 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 2400 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.
Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
