Abstract :
In this paper, a multi-band OFDM system for ultra-wideband communication (UWB) 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 sub-band, an OFDM modulation scheme is used to convey the information. An overview of the multi-band OFDM system and various system design trade-offs are discussed within this paper. In addition, bit precision requirements, power consumption estimates and performance results in realistic multi-path environments are provided for the multi-band OFDM system.
