Condición: Hervorragend. Zustand: Hervorragend | Sprache: Englisch | Produktart: Bücher | Recent research shows that 70% of the available spectrum is not utilized efficiently. The bandwidth gets expensive owing to shortage of frequencies. For efficient utilization of spectrum, we need to sniff the spectrum to determine whether it is used by primary user or not. The term cognitive radio refers to the adoption of radio parameters using the sensed information of the spectrum. There are three major categories of spectrum sensing techniques; transmitter detection, receiver detection and interference temperature detection. This book presents a survey of techniques suggested in the literature for spectrum sensing with a performance analysis of transmitter-based detection techniques. A Fuzzy logic based technique for primary user detection has also been proposed. In comparison with transmitter detection techniques purposed technique provides good results under low SNR values.

Hardcover. Condición: new. Hardcover. The sixth-generation (6G) communication systems are anticipated to provide network connectivity for an extensive range of use cases in a variety of emerging vertical industries. Consequently, a new set of challenging requirements and more stringent key performance indicators have to be considered, a novel architecture has to be designed, and unique enabling technologies shall be developed in order to fulfil the technical, regulatory, and business demands of the communication service customers.6G networks are expected to offer even faster speeds, lower latency, and greater capacity compared to 5G networks, which will enable new applications and use cases that are currently not possible. Improved quality of life by enabling various applications (emerging Internet of everything applications) such as healthcare, brain-computer interactions, and extended reality is the main focus of future wireless services. Quality of experience, latency, and reliability are the key requirements of these applications. To meet these diverse requirements there is a need to assist wireless systems with unique technologies. Self-sustaining wireless systems (intelligence, seamless and ubiquitous connectivity) and proactive-online-learning-enables systems (Intelligent analytics) are two trends in future wireless systems. The digital twin technology is one of the most promising technologies that can be instrumental in realizing the technical and business objectives of 6G communication systems.A digital twin is a virtual imitation of a physical object or system. In a wireless system, a digital twin can be used to model and analyse the behaviour of the network and its components, such as antennas, transmitters, receivers, sensors, and other devices in wireless networks. One of the key benefits of using a digital twin for a wireless system is that it can help network operators and engineers to optimize the performance of the wireless network by simulating different scenarios and configurations. Other benefits include improve efficiency, cost saving, and enhanced security. In 6G networks, a digital twin could be used to simulate and optimize the performance. This could include simulating different network topologies, testing the performance of different network protocols and algorithms, and optimizing the placement of network infrastructure.To create a digital twin of a wireless network, a detailed model of the network and its components must be developed, based on real-world data and conditions. This model can then be used to simulate the behaviour of the network under different conditions and settings and to visualize the results in real time.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Investigaciones recientes muestran que el 70% del espectro disponible no se utiliza de manera eficiente. El ancho de banda se encarece debido a la escasez de frecuencias. Para una utilización eficiente del espectro, necesitamos oler el espectro para determinar si es utilizado por el usuario principal o no. El término 'radio cognitiva' se refiere a la adopción de parámetros radioeléctricos utilizando la información sensada del espectro. Existen tres categorías principales de técnicas de detección del espectro: detección del transmisor, detección del receptor y detección de la temperatura de interferencia. Este libro presenta un estudio de las técnicas sugeridas en la literatura para la detección del espectro con un análisis del rendimiento de las técnicas de detección basadas en el transmisor. También se ha propuesto una técnica basada en la lógica difusa para la detección de usuarios primarios. En comparación con las técnicas de detección basadas en el transmisor, la técnica propuesta proporciona buenos resultados con valores bajos de SNR. 72 pp. Spanisch.
