IR-UWB technology has recently gain considerable interest in research institutes as well as in industries. It opens new horizon for new wireless applications, since it’s different than other wireless technologies, which they all consider by convention as narrowband comparing to it. IR-UWB transmitting very short pulses with ultra-wide bandwidth with very low duty cycles, this will give some advantages over conventional RF enabling IR-UWB to be the technology for RTLS, RFID, digital smart homes and other new promising wireless applications. In literature many wireless indoor applications can be classified as low to medium or high data rates, with also varying ranges from very short to medium ranges, briefly we can say that there is trade-off between three variables to judge any wireless link performance: Data rate, distance and Bite-error rate, and any applications of a given radio system can trade two of these variables at the cost of third. Fortunately that the IR-UWB definition is flexible and its parameters can be tuned according to Quality of service criteria threshold (BER) or to transmit in different data rates. That’s will make IR-UWB considered as good candidate as cognitive radio. In this research paper, will investigate the flexibility of IR-UWB parameters and how its signal parameters can be dynamically changed according to specific BER threshold to support adaptive IR-UWB scheme for cognitive wireless network applications. Simulated results and real-time point to point IR-UWB radio experiments will be conducted as proof of concept, showing that cognitive IR-UWB system is feasible and is promising technology to combine many wireless communications application in one novel platform.
