Low-Complexity Ultra Wideband Communications

Abstract

Low-complexity, low power UWB radios are required for LDR short-range applications. Potential low power air interfaces candidates are impulse radio UWB and FM-UWB. FM-UWB is a constant-envelope UWB communication system using double FM: digital FSK followed by high modulation index analog FM to create a constant-envelope UWB signal. The system is intended for low data rate (< 100 kbps), short-range (< 10 m) personal area network systems. Due to its simple architecture, FM-UWB radio will be low cost and have low power consumption
