Multiple carrier ultra‐wideband systems using an optical pulse modulation scheme

This study proposes a new optical pulse modulation scheme for multiple carrier ultra‐wideband (MC‐UWB) wireless systems to achieve a reliable high‐bit‐rate transmission. The scheme can decrease the system complexity and lowering cost. Moreover, the UWB receiver is adapted with a modified single‐user correlation detector to recover original data signal by a narrow carrier spacing. Finally, we set up a practical experimental system to prove our proposed scheme. Experiment results demonstrate that the scheme can provide high spectral efficiency and reduce interference noise for MC‐UWB wireless communications. © 2010 Wiley Periodicals, Inc.
