A multi-band band stops filtering (MB-BSF) characteristics with modified dual-polarized dipole antenna using the grounded coplanar waveguide (GCPW) filter for the 3G, 4G, and 5G base station applications are explored in this research paper. Firstly, the modified dipole arms are arranged in a crisscross manner to generate orthogonal polarizations with CPW feed designed to operate in the frequency band of 1.6-3.6 GHz. Secondly, meandered slot GCPW is patterned on the modified dipole antenna and is modeled to provide band stop characteristics with sharp roll-off for 3G, 4G, and 5G. As an outcome, the anticipated antenna is operating in the band of 1.6–2.78 GHz and 3.2–3.8 GHz for VSWR < 1.6 with a guard band of 2.85–3.18 GHz. The proposed antenna provides the isolation of more than 30 dB, the half-power beam width of 700±10, and realized gain of 8.73 dBi throughout the operating band of 3G, 4G, and 5G for Base Transceiver Station (BTS) applications.

This paper proposes an event-triggered control approach for the application of vertical wall-perching of an aerial robot. A finite time position tracking controller is developed for nano-quadcopter. A recursive finite time stable manifold has been designed for the convergence of the error states to zero in finite time. Next, sliding mode control laws for all the control inputs are derived from the designed stable sliding manifold. Furthermore, from the Lyapunov stability theory, periodic event-triggering conditions are derived to minimize resource utilization. The Periodic event trigger controller provides the control laws next trigger time. The perching of nano-quadcopter will help in long time surveillance in remote locations.

Intelligent reflecting surfaces(IRS) have received a lot of attention in next generation communication networks as they provide a cost efficient way to improve the channel conditions. While terrestrial IRSs provide improvements, aerial IRSs where the IRS is mounted on an unmanned aerial vehicle(UAV) provide higher coverage and network reach. In this paper, a system model where the base station(BS) and user equipment(UE) can communicate over the direct BS-UE link, as well as an indirect BS-IRS-UE link is considered, where the IRS is mounted on a UAV. The coverage probability is derived for the system. The coverage range i.e, the height of the UAV beyond which the coverage is zero is also derived. Monte Carlo simulations are performed to verify the theoretical expressions and several inferences are drawn based on the results.

Magnetic resonance imaging (MRI) is a popular non-invasive diagnostic tool used for detecting health problems in human bodies. 90% of the world population do not have access to MRI due to high cost involved in it. High field MRI (3T and above) involves bulky and expensive equipments which are unaffordable in economically backward nations. Presently, 1.5T MRI has the largest market share, at 47 percent by value and 52 percent share by volume, since it provides adequate image quality at a comparatively low cost. However, the scan-time in 1.5T is quite long. Lower scan-time in 1.5T MRI can be obtained by increasing the signal-to-noise ratio (SNR). One of the techniques of improving the SNR of MRI is deployment of metasurfaces for enhancing the RF magnetic field in the region of interest (ROI). In this work, we demonstrate the design of a single-layered thin metasurface which exhibits resonance at 63.8 MHz, the Larmor frequency of 1.5T MRI. Numerical simulations using finite integration technique show twenty-fold increase of magnetic flux density on the surface of a human phantom. The increase in the RF magnetic flux density results in improvement of signal-to-noise ratio (SNR) which can make MRI more efficient, affordable and accessible.

In this paper, a novel V-shaped slotted single, dual band frequency reconfigurable antenna is presented for upcoming 5G and C-band applications. The antenna operates around 3.9 GHz (5G), around 5.5 GHz Wireless Local Area Networks (WLAN) and 6.37 GHz for C-band applications. For obtaining the reconfigurability in the designed structure a V-shaped slot is etched on hexagonal shape radiating element and a PIN diode is adopted. If the PIN diode is ON state, the proposed radiating structure provides dual band operations in the frequency range of 3.49-4.46 GHz with centre frequency around 3.9 GHz and 5.59-7.59 GHz with centre frequency around 6.37 GHz with a bandwidth of 970 MHz, 2000 MHz respectively, else provides a single band operation in the frequency range of 4.03-7.14 GHz with centre frequency around 5.5 GHz with bandwidth of 3110 MHz. A hexagonal shape radiating patch element is incorporated on FR-4 substrate with overall size of (30 x 28 x 1.6) mm3. A comparative analysis with cutting edge work demonstrates that the presented designed antenna structure has the advantages of compact size, improved bandwidth and gain.

The fundamental frequency (pitch) is essential in determining speech quality. This paper proposes a modified circular average magnitude difference function (CAMDF) based algorithm for estimating the pitch of the speech signal. The performance of the proposed algorithm has been compared with autocorrelation function (ACF), average magnitude difference function (AMDF), and CAMDF based pitch detection methods by incorporating them into an analysis-synthesis system for speech signal. The proposed method has a lower gross error of 5.33%, 4.7%, and 0.83 % compared to AMDF, ACF, and CAMDF methods. Also, the synthesized speech quality of the proposed algorithm in respect of subjective and objective tests is superior with respect to other algorithms.

Using well-calibrated electro-thermal simulations, the impact of self-heating on distortion parameters such as second-order harmonic distortion (HD2) and third-order harmonic distortion (HD3) characteristics has been investigated in this work. The presence of the self-heating effect degrades the RF characteristics of InGaAs nanosheet FETs. The influence of TA on distortion parameters is also examined by altering the ambient temperature (TA) from 300K to 360K. Our simulation anticipates a shift in distortion performance of InGaAs nanosheet FETs by increasing HD2 and HD3 by 25% and 4%, respectively, for a temperature increase of 60K above room temperature. With the introduction of highly thermally conducting buried oxide materials, the change in distortion performance of the InGaAs nanosheet MOSFET has also been observed with the rise in the minima of HD2 and HD3.

Electrocardiology (ECG) is useful for deriving a multitude of cardiac functions, and widely used for ambulatory health monitoring. The main hindrance for automatic measurement utilizing ECG is signal quality which gets affected with various artifacts like patient motion, poor skin-electrode contact. While various of ECG signal quality assessment (SQA) techniques are available, most of the works use computationally intensive and memory demanding techniques like wavelet, autoencoders, mode decomposition techniques etc. This paper exhaustively uses various entropy features, which are information rich, computationally lightweight and promising for the application. Secondly, evidence of multiclass ECG SQA is occasional. This paper describes the use of 20 entropy features for 3-class ECG SQA. Total 400 records from Computing in Cardiology (CinC) 2011 challenge, each of 6 leads and of 10 s duration per lead was evaluated, with a blind test accuracy of 75.43% for 3 class and 97% for 2-class SQA. It was found that the entropy features outperform the wavelet and AE features, and random forest provides superior performance over support vector machine and k-NN. The present research provides improved results over few published works on ECG SQA using CinC2011 dataset.
