Overview of ultra-wideband transceivers—system architectures and applications

The Ultra-WideBand (UWB) technique, which offers good energy efficiency, flexible data rate, and high ranging accuracy, has recently been recognized as a revived wireless technology for short distance communication. This paper presents brief overview of two UWB techniques, covering Impulse-Radio (IR-UWB) Frequency-Modulation (FM-UWB) methods. link margin enhancement Very-WideBand (VWB), power consumption reducing chirp UWB, are also introduced. Then, several potential applications IR-UWB with transceiver architectures addressed, including rate proximity communication secure connectivity. With fine-ranging energy-efficient features, the is highly promising mobile Internet Things (IoT) applications.
