- FM-UWB
FM-UWB is a modulation scheme using double FM: a low-modulation index digital FSK followed by a high-modulation index analog FM to create a constant-envelope UWB signal.
FDMA techniques at the sub-carrier level may be exploited to accommodate multiple users. The system is intended for low (1–100kbit/s ) and medium (100–1000 kbit/s) bit rate, and short-range WPAN systems.The technology, developed atCSEM , is paving the way for true low-powerLDR-UWB communication devices.References
