Study on different implementations of UWB wireless communication system

The technology of ultra-wideband (UWB) has been widely used for its advantages about high transfer rate, large capacity, low cost, low-power etc. There are three kinds of implementation technologies: impulse radio (IR), Direct Sequence Code Division Multiple Access (DS-CDMA) and multiband orthogonal frequency division multiplexing (MB- OFDM). In this paper, features and solutions of UWB system are demonstrated and comparative study on these implementations are presented.
