Multi-band OFDM: a new approach for UWB

In this paper, a multi-band OFDM (MB-OFDM) system for ultra-wideband communication is described. In this system, the UWB spectrum is divided into bands that are 528 MHz wide and the data is transmitted across the bands using a time-frequency code. Within each subbands using a time-frequency code. Within each subband, an OFDM modulation scheme is used to transmit the information. An overview of the MB-OFDM system and various systems design consideration are discussed. In addition, the performance results in realistic multi-path environments are provided for the MB-OFDM.
