This paper is about the chip for the impulse radio UWB positioning system compliant with IEEE 802.15.4a global standard that not only realizes communication but also ranging function with low cost and low power. The impulse radio UWB positioning baseband chip manufactured through the TSMC 0.13 um mixed-signal CMOS process. It has been designed for the direct up-down conversion transceiver. Hence it...
The ranging and positioning systems for the LR WPAN (low-rate wireless personal area network) have been one of the attracting issues for indoor location applications. In order to support the ranging functions in WPAN, IEEE 802.15.4a Task Group has released new standard of alternative PHY (Physical layer) and amendment of MAC (medium access control) with IR-UWB (impulse radio ultra wide band) signals...
The ranging functions for the low rate WPAN have been one of the attractive issues to provide diverse applications. The IEEE 802.15.4a Task Group has specified alternative PHY and partially modified MAC using UWB signals to support more precise ranging accuracy. Based on the standard PHY and MAC of IEEE, this paper describes the implementation of the IEEE 802.15.4a MAC and for ranging and data communication...
