“…This paper can be integrated with other papers regarding unique geometric scattering models for MIMO channels [4,5]. Some studies work around modern communication with jammers [15,21,31,36]. This paper and future studies will complement these papers and provide different points of view on this subject.…”

“…The second condition is to combines unlicensed and licensed technology. The meaning of this combination is to manage a significant number of the wireless device under specific macro cell, without sharing any Physical Upload Shared Channel (PUSCH), Without sharing a common scheduler, and also without any Demodulation Reference-Signals (DM-RS), which help to run algorithms for estimating and offsetting interfering, like Minimum Mean Square Error-Interference Rejection Combining (MMSE-IRC) [13][14][15]. For example, the use License Assisted Access (LAA) protocol [16,17], or Device-To-Device (DTD) technique [18], to get a significant channel capacity, in an environment with multiinterferences.…”

“…In recent years, significantly advanced interference cancellation techniques, such as MMSE-Interference Rejection Combining (MMSE-IRC) and MMSE-Maximal Ratio Combining (MMSE-MRC), have been developed and implemented in advanced LTE [15,36,37]. The next step is the new algorithm interference, and anti-jamming generation is required, especially under the assumption of TDD access and Ultra-Reliable and Low-Latency Communications (URLLC) in 5G requirements.…”

Many communication systems are based on the Multiple Input, Multiple Output (MIMO) scheme, and Orthogonal Space–time Block Transmit diversity Coding (OSTBC), combined with Maximal Ratio Receive Combining (MRRC), to create an optimal diversity system. A system with optimal diversity fixes and optimizes the channel’s effects under multi-path and Rayleigh fading with maximum energy efficiency; however, the challenge does not end with dealing with the channel destruction of the multi-path impacts. Susceptibility to interference is a significant vulnerability in future wireless mobile networks. The 5th Generation New Radio (5G-NR) technologies bring hundreds of small cells and pieces of User Equipment (UE) per indoor or outdoor local area scenario under a specific Long Term Evolution (LTE)-based station (e-NodeB), or under 5G-NR base-station (g-NodeB). It is necessary to study issues that deal with many interference signals, and smart jammers from advanced communication equipment cause deterioration in the links between the UE, the small cells, and the NodeB. In this paper, we study and present the significant impact and performances of 2×2 Alamouti Phase-Shift Keying (PSK) modulation techniques in the presence of an interferer and a smart jammer. The destructive effects affecting the MIMO array and the advanced diversity technique without closed-loop MIMO are analyzed. The performance is evaluated in terms of Bit Error Rate (BER) vs. Signal to Interference Ratio (SIR). In addition, we proved the impairment of the orthogonal spectrum assumption mathematically.

Massive Multiple Input Multiple Output (M-MIMO) systems specifically refers to a practical technique for sending and receiving more than one data signal simultaneously over the same radio channel by exploiting multipath propagation". It depends on several antennas for transferring varied data streams simultaneously. With the increase in count of antennas, the energy or power utilization also gets increased. Thus, it becomes necessary to select optimal transmit antennas that exist as the great challenge in M-MIMO systems. This work introduces a new "Hybrid Sea Lion-Whale Algorithm (HS-WA)" for selecting the optimal transmit antenna by considering the multi-objectives, which increases both capacity and efficiency. The adopted scheme is the combination of both "Whale Optimization Algorithm (WOA) and Sea Lion Optimization Algorithm (SLnO)" that optimizes the antenna's count and moreover, it finds out "which antenna to be selected". At last, the supremacy of presented model is confirmed over existing models in terms EE and capacity analysis.
