“…So far, wireless location techniques mainly include methods based on different network parameters such as cell-ID, signal strength of arrival, and time of arrival [29,30] . For example, Yao and Yang [31] compared different technologies relating to mobile terminals' location and obtained the mobile terminal location by parsing information from relevant parameters. Guo et al [32] established a robot perception system that could obtain primary locations via aural sensors and continuously achieve optimization by using charged-coupled device (CCD) cameras.…”

The growing computing power, easy acquisition of large-scale data, and constantly improved algorithms have led to a new wave of artificial intelligence (AI) applications, which change the ways we live, manufacture, and do business. Along with this development, a rising concern is the relationship between AI and human intelligence, namely, whether AI systems may one day overtake, manipulate, or replace humans. In this paper, we introduce a novel concept named hybrid human-artificial intelligence (H-AI), which fuses human abilities and AI capabilities into a unified entity. It presents a challenging yet promising research direction that prompts secure and trusted AI innovations while keeping humans in the loop for effective control. We scientifically define the concept of H-AI and propose an evolution road map for the development of AI toward H-AI. We then examine the key underpinning techniques of H-AI, such as user profile modeling, cognitive computing, and human-in-the-loop machine learning. Afterward, we discuss H-AI's potential applications in the area of smart homes, intelligent medicine, smart transportation, and smart manufacturing. Finally, we conduct a critical analysis of current challenges and open gaps in H-AI, upon which we elaborate on future research issues and directions.

“…In this experimental Work based on VST 5644R we tried to investigate some of these simulation parameters like spreading factor of WCDMA which affects performance of the system as a whole. Using VST 5644 at Physical Layer WCDMA Link [2][3][4][5] can be implemented. This implementation includes firstly decoding the downlink modulated WCDMA received signal, analyzing the received signal pattern in software LabVIEW 2012, calculating error vector magnitude (EVM) and relative input power.…”

“…Third generation system are designed for multimedia communication at high data rate. WCDMA technology is the most widely used third generation system which is spreading over a wide bandwidth by multiplying the user information with spreading sequence in WCDMA [2][3][4][5]. Due to increasing the demand of high data rate, more complex modulation schemes are used in various wireless communications resulting tightened error vector magnitude (EVM) requirement.…”

“…A BTS will transmit unique channels to many mobile users, and each mobile receiver distinguish it own channel from all other channels by using channelization codes, known as orthogonal variable spreading factor (OVSF) codes. Each channel originating from a BTS or from UE multiplied with different OVSF code [2], [6][7] also known as spreading factor. The length of OVSF code in WCDMA varies from 4 to 512 chips.…”
