In the 5G network deployment, due to the limited availability of frequency spectrum, mobile users and internet-of-things (IoT) devices will transmit on the same frequency bands, necessitating more stringent in-band interference management to facilitate interference-free communication. In order to ensure that high-power user equipment (UEs) accessing the shared 5G uplink channel are able to communicate without disruption and without interfering with low-power devices, it is imperative to undertake in-band emissions analysis and control. This paper explores the issue of in-band emission interference, which pertains to the interference that arises in unallocated sub-bands within a specific bandwidth. Specifically, this investigation delves into the modeling approach and regulated in-band emissions within a non-standalone (NSA) 5G network. To verify compliance with 3GPP requirements for in-band emissions regulations, an over-the-air (OTA) testing system is employed to examine in-band emissions in the physical uplink shared channel (PUSCH). The study employs various resource block distributions, offsets, and modulation techniques within the specified NR channel bandwidth. All simulations are based on 3GPP specifications.KEYWORDS: Cyclic-prefix orthogonal frequency division multiplexing (CP-OFDM)Frequency spectrumIn-band emissionsNon-standalone (NSA) networkOver-the-air (OTA) measurementPhysical uplink shared channel (PUSCH)Resource block (RB) allocationTransmission bandwidth Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationNotes on contributorsPermvir SinghPermvir Singh received his MSc degree from the University of Sussex, UK in 2020.

In this approach, the denominator coefficients of the higher-order system (HOS) are estimated using the MSM, while the numerator coefficients are computed using the SEM. The suggested approach is based on the MSM, which guarantees the stability of the estimated model if the actual model is stable. The MSM also makes sure that important factors of the original plant, such as dominant poles and stability, are retained in the reduced order system (ROS). The suggested approach is compared to several current conventional reduction methods using error indicators, and the smallest performance error indices values reflect the supremacy of the method. The transfer function (TF) of the ROS is then used to design controllers by employing the moment matching technique. When the controller designed with the approximated model is applied to the real HOS, it indicates that the response of the closed-loop system of the real model entirely overlaps with the response of the reference plant. To further demonstrate the efficiency of the proposed schemes, time-domain specifications are produced and time responses are plotted.KEYWORDS: Controller designHigher order modelMihailov stability methodModel order reductionReduced order modelStability equation method Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe authors confirm that the data supporting the findings of this study are available within the article.Additional informationNotes on contributorsSunil Kumar GautamSunil Kumar Gautam received the Btech degree in electrical engineering from Uttar Pradesh Technical University, Uttar Pradesh, India, in 2013, and the Mtech degree in control and instrumentation from Motilal Nehru National Institute of Technology, Allahabad, Uttar Pradesh, India, in 2019.

An EMG signal-based system encapsulates different domains of signal acquisition and processing, statistical analysis, and control systems in a single framework. This survey attempts to highlight and distinguish the time- and frequency-based signal processing according to the applications of EMG signals. When EMG signals are used for clinical assessment, time–frequency analysis involves transforming the signals in different domains and extracting useful physiological information. On the other hand, the concept of time and frequency deals with extracting time, frequency, or time–frequency-based features when EMG signals are used for pattern recognition-based control applications such as robotics and augmented reality. It is often very difficult and confusing to distinguish and establish a clear understanding between these domains reported in various literature. Hence, this study first presents different signal acquisition systems and pre-processing techniques, followed by comprehending the concepts in time, frequency, and time–frequency-based approaches based on the applications. Next, the review of various post-processing techniques, different feature extraction routines, and a survey of different classifiers used in the pattern recognition step is done. The work concludes with a study of innovative applications of EMG signals reported in recent years, provides an overview of EMG signal-based limb prosthetics, and suggests a few futuristic research ideas.KEYWORDS: Biomedical engineeringData acquisitionElectromyographyFeature extractionPattern classificationProstheticsSignal processing Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationNotes on contributorsAnil SharmaAnil Sharma received a BTech degree in electronics and communication and an MTech degree in mechatronics engineering.
