FM-UWB
Encyclopedia
FM-UWB is a modulation scheme using double FM
: low-modulation index digital FSK followed by high-modulation index analog FM to create a constant-envelope UWB signal. FDMA techniques at the subcarrier level may be exploited to accommodate multiple users. The system is intended for low (10–50 kbit/s) and medium (50–250 kbit/s) bit rate, and short-range WPAN systems.
The technology, developed at CSEM
, is paving the way for true low-power LDR-UWB communication devices.
Frequency modulation
In telecommunications and signal processing, frequency modulation conveys information over a carrier wave by varying its instantaneous frequency. This contrasts with amplitude modulation, in which the amplitude of the carrier is varied while its frequency remains constant...
