NOMA/OMA Mode Selection-Based Cell-Free Massive MIMO

, 2019
In this paper, non-orthogonal-multiple-access (NOMA)-based cell-free massive multiple-input multiple-output (MIMO) is investigated, where the users are grouped into multiple clusters. Exploiting conjugate beamforming, the bandwidth efficiency (BE) of the system is derived while the assumption that the users performing realistic successive interference ...

Performance and Architectural Tradeoffs in Scalable Cell-Free Massive MIMO

IEEE Access
The massive number of APs is often perceived as a complexity bottleneck for the scalable deployment of Cell-free (CF) systems. In this context, we propose various system-level results and valuable insights on some of the multidimensional design ...

Cell-free massive MIMO surveillance systems

Wireless surveillance, in which untrusted communications links are proactively monitored by legitimate agencies, has started to garner a lot of interest for enhancing the national security. In this paper, we propose a new cell-free massive multiple-input multiple-output (CF-mMIMO) wireless surveillance system, where a large number of distributed multi ...
