We design an impulse-radio ultra-wideband (IR-UWB) receiver, especially targeting IEEE 802.15.4a standard for ranging and low-rate communication. We first discuss the IEEE 802.15.4a IR-UWB signal and suggest the full-digital coherent receiver due to its advantages of better performance and accurate ranging. We then propose analog-to-digital converter (ADC) requirements for our receiver.
This paper discusses ranging for IEEE 802.15.4a impulse-radio ultra-wideband (IR-UWB) system, especially targeting implementation. The essential capabilities for ranging are the ranging counter and determination of the arrival time of a signal at the receiver, which are implemented in our full-digital coherent IR-UWB system. The ranging measurements verify our design for ranging.
This paper investigates LPF requirements for IR-UWB systems, especially targeting the IEEE 802.15.4a standard. We first suggest the architecture for IEEE 802.15.4a IR-UWB to construct a frame at the transmitter and successfully decode the transmitted bits at the receiver. We then relieve the LPF requirement, focusing on implementation at low-complexity and small size. Simulation results verify our...
