| الوصف: | Multiple-input multiple-output (MIMO) is an indispensable technology for deploying the pervasive connectivity sought for fifth-generation (5G) and beyond communication systems. By relying on a large number of antennas, massive MIMO schemes can implement space division multiple access (SDMA) to serve spatially separated users with a single frequency–time resource block, thus, leading to incredible spectral and latency enhancements. Nevertheless, there are certain communication scenarios, such as ultradense deployments or environments with users sharing overlapping angular positions, where spatial multiplexing becomes unrealizable through SDMA alone. These challenging scenarios motivate the exploitation of different domains and technologies. In particular, power-domain non-orthogonal multiple access (NOMA) and rate-splitting multiple access (RSMA) have appeared as strong candidates for extending the capabilities of MIMO systems and enabling resource-efficient simultaneous transmissions even to overlapping users. In parallel development, a disruptive concept of an intelligent reflecting surface (IRS) has arisen as a method to manipulate electromagnetic propagation through reconfigurable, low-power, subwavelength reflecting elements. As their main feature, the properties of IRSs can be dynamically tuned and harnessed to attack harsh phenomena of wireless channels and accomplish diverse objectives, enabling communication environments with optimized signal radiation. Driven by the promising capabilities of the above-mentioned technologies, this doctoral dissertation focuses on studying and developing novel transmission schemes based on the synergy between NOMA, RSMA, and IRSs, and their application to next-generation multiuser MIMO communication networks. This research work starts by investigating practical issues of imperfect successive interference cancellation (SIC) on a downlink multicluster massive MIMO-NOMA network. Through an in-depth theoretical analysis, exact closed-form expressions are derived for the ... |
