Mohamed Ali, Heba Shawkey, Abdelhalim Zekry . A Survey on FM-UWB Transceivers. International Journal of Computer Applications. 61, 6 ( January 2013), 1-5. DOI=10.5120/9929-4560
This paper surveys the research on frequency modulated ultra-wideband (FM-UWB) transceivers. FM-UWB system uses low modulation index digital FSK followed by high modulation index analog FM to generate a constant envelope UWB signal with a flat power spectral density and steep spectral roll-off. FM-UWB can be seen as an analog implementation of a spread spectrum system with spreading gain equal to the modulation index. FM-UWB system is suitable for low data rate and short-range applications. The advantages of FM-UWB system such as low power consumption, very low radiated power (?41. 3 dBm/MHz), good coexistence with other existing wireless technologies, and robustness to interference and multipath making it suitable for Wireless Body Area Network (WBAN) in medical applications.
