Abstract:

UWB based on chirp waveform has the advantages of low cost,low power consumption and high processing gain. A UWB system based on multi-chirp waveform is employed to construct a multi-user UWB system,which enables the system gain merits of both IR-UWB as well as OFDM-UWB. System performance for multi-user UWB using multi-chirp waveform is theoretically analyzed with details. Simulation results are given to show that such a system outdoes traditional UWB in the aspect of mitigating multi-user interference.

Key words: ultra-wideband, multi-user interference, chirp signal, surface-acoustic device
