In this letter, we propose a cooperative relaying system (CRS) based on non-orthogonal multiple access (NOMA) which uses an amplify-and-forward relay. This letter proposes novel detection scheme in the received signals of two consecutive time slots at destination is applied. We calculate asymptotic outage probability and derive diversity order for each symbol. Simulations show that our has much better performance than NOMA-based CRS with decode-and-forward (DF) Also, ergodic sum rate...

Abstract In this paper, we study the performance of a cooperative non‐orthogonal multiple access (NOMA) system with dedicated relay. This relay is full duplex (FD) and works in an amplify‐and‐forward (AF) mode. Our NOMA consists two users where one them near to base station other assumed be far from station. We derive exact expressions for outage probability ergodic achievable rate users. The simulations demonstrate that case imperfect self‐interference cancelation, our proposed FD‐AF...

In this paper, we find trajectory planning and power allocation for a vehicular network in which an unmanned-aerial-vehicle (UAV) is considered as relay to extend coverage two disconnected far vehicles. We show that two-user with amplify-and-forward (AF) relay, non-orthogonal-multiple-access (NOMA) always has better or equal sum-rate comparison orthogonal-multiple-access (OMA) at high signal-to-noise-ratio (SNR) regime. However, the cases where i) base station (BS)-to-relay link weak, ii)...

A balun inductorless wideband low noise amplifier (LNA) with active loads is proposed for multi-standard radio applications. The cancelling and current reuse techniques are combined to mitigate the need high power consumption in conventional LNAs. This adds a degree of freedom transconductance common gate stage (g mCG ). As result, lower g without degrading input matching, allows large scaling factor source (CS) technique. Post-layout simulation results LNA circuit 180 nm RF CMOS process...

In 5G wireless communication networks, Non-Orthogonal Multiple Access (NOMA) has attracted much attention in recent years. This paper investigates physical layer security of a NOMA system with Full Duplex Relay (FDR) and Half (HDR). consists one eavesdropper two legal users where dedicated FDR (or HDR) assists far user. order to characterize the secrecy performance considered scenario, new exact expressions are derived for Secrecy Outage Probability (SOP) both HDR systems. Monte Carlo...

The sixth generation (6G) of wireless communication networks should deliver higher data rates and spectral efficiency for novel demands utilizations. Cell free massive MIMO is one promising technique to achieve these goals. Distribution base stations (BSs) in this system creates more better coverage users than the conventional cellular system. On other hand, deep learning methods have been proven be competitive frameworks comparison traditional optimization approaches applications. In paper,...

This paper presents a MEMS based oscillator with automatic amplitude control. Previously demonstrated ring shape anchored contour mode disk resonator is evaluated and some of its analytical aspects are extracted as well equivalent electrical circuit for further transistor level simulations. Due to 180° phase change the resonator, sustaining amplifier should provide another oscillation build up. As will be shown, motional resistance which determines minimum required gain circuit, very high...

With a growing emphasis on human identification, iris recognition as biometric identification has recently received increasing attention. Feature vectors are extracted from templates and used for classification purpose. But efficiency of operation depends exclusivity feature vectors. We have improved features by using new filter bank applying locally Principle Independent component analysis features. Simulation results show improvement decreasing false match rate in matching level.

Object removal in image and video sequences has attracted many researchers processing.
