Binary GA for Sidelobe Reduction and Null Steering in 5G Array
Abstract: This paper presents a comprehensive performance evaluation of a Binary Genetic Algorithm (BGA) for optimizing radiation characteristics of an active phased array antenna used in fifth-generation (5G) wireless communication systems. The primary objective is to achieve effective null steering while maintaining the desired main beam direction and simultaneously reducing the side lobe level (SLL). These improvements are essential for minimizing co-channel interference, enhancing spatial selectivity, and improving the Signal-to-Interference-plus-Noise Ratio …

A Low Delay Two-Channel Quadrature Mirror Filter Bank using IIR Filter
Abstract: IIR filters have the advantage of low delay, high selectivity and stopband attenuation as compared to their counterpart FIR filters. In the present work, a low delay two-channel Quadrature Mirror Filter (QMF) bank using IIR filter has been proposed. The IIR prototype filter has been designed by approximating the FIR lowpass filter using the least square approximation. The length of the IIR filter has been selected using the bi-section method. …

Side Lobe Reduction using Bacterial Foraging Optimization
Abstract: AbstractTo meet the need for long-distance communication, the directive characteristics and radiation pattern of the antenna must be improved. By arranging the antenna elements in an electrical or geometric pattern, such that the radiated energy of the radiation elements vector added in the desired direction of propagation and canceled in the unwanted direction, results in a better-designed antenna array. The elements of the antenna array may be uniformly or non-uniformly …

An Improved Power Line Interference Reduction Approach Based on Combination of Mirror Extension and IIR filtering Through a Data Driven Mechanism
Abstract: Electrocardiogram (ECG) is a clinical sign monitoring measurement of the cardiac abnormalities. Like other biomedical signals, the ECG signal is also contaminated by various kinds of noise and artifacts such as power line interference, base line wandering, muscle artifacts and electrode artifacts. The present paper proposes a scheme for power line interference (PLI) reduction from ECG signal. It makes use of the concept of mirror method, empirical mode decomposition (EMD) …
