| description |
Impulse-based ultra-wideband (UWB) can be utilized to support different wireless range with varied data rates and guaranteed received signal quality if the generated pulses tuned carefully. The unique physical advantages of generating a train of very narrow pulses ( in nanoseconds)in ultra-wideband signal are proven in many literature studies to be utilized in different wireless sensing applications such as precise object tracking, high data rate wireless transmissions, medical radar imaging, and military intrusion detections. The motivations of this study can be understood as currently, UWB technology is standardized in two different IEEE protocols as IEEE 802.15.3a for high data rates using Orthogonal Frequency Division Multiplexing (OFDM) modulation and IEEE 802.15.4a for low data rates using time hopped modulated train of pulses.This study is motivated by the optimization of IEEE 802.15.4a to support higher rates as well as low rates, as also preserving the quality of the received signal.
The problem statement of this research is inspired by the need to have a single UWB solution standard to be tuned to support different applications requirements of data rates and quality of service (QoS) instead of two different protocols. The proposal solution proves the concept of Adaptive PHY-MAC aware UWB design and architecture by tuning the generated train of pulses in time-hopping spread spectrum techniques to support the requarments of different data rates and QoS communications scenarios. The research methodology has investigated the physical parameters of generating a train of very short pulses in ultra-wide frequency ranges then, and it proceeds to propose link budget template design for the purpose of obtaining an adaptive IR-UWB communication system. The objective of this study is intended to utilize a single UWB solution for different data rates and QoS requirements, will reduce the costs of UWB applied over WSN, also will allow cognitively of the wireless node to maintain its operations under a dynamically changing environment in future scenarios. Proposed design of the link budget template for the adaptive IR-UWB communication system is simulated, and improvements are shown to be reached from 10 to 50% of the BER with the suitable RAKE receiver structure. Also, tuning the IR-UWB signal physical parameters with the best matching values for certain BER or data rates requirements can improve the BER up to 65%. Simulated scenarios results of data rates range from 20 to 200 Mbps with maximum distances of 30 m and BER requirement not exceeding ( showed that the best performance is achieved by tuning the pulse modulation to 2PPM. Real-time simulation analysis of the received packets in the indoor scenario of range between 12 to 100 meters, showed that the best-achieved throughput obtained for data rates between 110kbps to 6.8 Mbps. This proposed design clearly describes the productivity of the UWB communication link through the simulation of IEEE 802.15.4a UWB in OMNET-MIXIM and the IEEE 802.15.3a in MATLAB and SIMULINK.MATLAB coding is used to determine the data transmission measurable factors (i.e., parameters), and the SIMULINK is used as prototype proof-of-concept in a real-time simulation environment. The results showed that the performance of the time-hopped UWB communication could be enhanced significantly when properly choosing the sitting of the physical parameters of the pulse generations under different applications and channel models constraints. |
