Comparative Evaluation of Bit Error Rate (BER ) in UWB
UWB (Ultra Wide Band) technology is a reliable transmission scheme for wireless communication with high data rates. It is called as impulse radio, impulse radar or carrier free ultra-high resolution. UWB occupies a bandwidth of more than 25% of a center frequency, or more than 1.5GHz. It is a carrier free (base band) technique, which will greatly reduce the complexity and cost of transceiver. UWB can be characterized with ultra-short duration pulses called monopulse which has excellent immunity in interference from sensitivity or multipath effects or fading problem.
