Coronary Artery Disease is the type of cardiovascular disease (CVD) that happens when the blood vessels which stream the blood toward the heart, either become tapered or blocked. Of this, the heart is incapable to push sufficient blood to encounter its requirements. This would lead to angina (chest pain). CVDs are the leading cause of mortality worldwide. According to WHO, in the year 2019 17.9 million...
Dynamic link adaptation techniques or adaptive modulation technique, where the modulation signal transmission is adjusted dynamically in accordance with the changing channel conditions that ultimately helps in improving the capacity of a channel. The Symbol Error Rate (SER) curves and capacity performance of different modulation schemes are analyzed using adaptive modulation. Adaptive modulation is...
Over the past few decades, the technological advancements in cell phones have brought a dramatic variation in life. Innovative applications and enchanting services provided by smartphones makes it the most ubiquitous consumer electronic device. Therefore smartphone has become paramount source for accessing, storing and sharing of business, personal, social, entertainment and official data. The complexities...
Nonlinearities play an imperative role in performance of wireless communication systems. In this paper, High Power Amplifiers (HPA) have been used to check the performance of the proposed system by analyzing its amplitude, phase and their joint distortions using Multiple-Input Multiple-Output (MIMO) wireless communication system. This paper takes-in account the overall effects of HPA that provokes...
Ultra Wideband (UWB) is a communication technique that uses a very narrow radio pulses for communication over a large bandwidth between transmitter and receiver. UWB technique is gaining popularity day by day because of its certain characteristics like simple architecture, cost reliability and low power consumption which is quite desirable in the field of short range wireless communication. Transmitting...
Nonlinearities in wireless communication channels foil the performance of the communication systems either at the transmitter or receiver end. This paper explains the concept of the transmitter-side nonlinearities that are induced by the High Power Amplifiers (HPA), the final stage at the transmitter side of the communication system. HPA nonlinearities create in-band and out-of-band distortions in...
