|Issue Date:||2003||Citation:||Chin, F.,Zhi, W.,Ko, C.-C. (2003). System performance of IEEE 802.15.4 low rate wireless PAN using UWB as alternate-PHY layer.

This paper proposes a UWB-based alternate PHY layer for 802.15.4 Low Rate Wireless Personal Area Network (LR-WPAN) system with the intention to enhance such WPAN system with better location positioning capability. The proposed UWB transceiver operates in the first 500MHz band, 3.1-3.6GHz, within the FCC allocated UWB band. Original 802.1 5.4 code position modulation scheme is slightly modified to 2-PPM to cater UWB transmission. A simple peah detector based receiver is employed to sample and decode the transmitted symbol. Extensive simulation over IEEE 801.15.3a UWB channel models showed that the proposed UWB based Alternate PHY layer can support 802.15.4 250kbps 16-byte packet transmission over WPAN range of 5m with 10% PER. It is also illustrated that, in general, PER increases over longer communication range and over longer channel delay spread. © 2003 IEEE.||Source Title:||IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, PIMRC||URI:||http://scholarbank.nus.edu.sg/handle/10635/71930||ISBN:||0780378229||DOI:||10.1109/PIMRC.2003.1264319|
