Abstract :
Low-complexity, low power UWB radios are required for low data rate short-range applications. 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 signal. The system is intended for low data rate (<; 250 kbps), short-range (<; 10 m) personal area network (PAN) systems. Due to its simple architecture and relaxed hardware specifications, FM-UWB radio has the potential for low power consumption which is illustrated using two circuit implementation examples.
