An uplink multiple-access method for a centralized ultra-wideband (UWB) radio network is studied. The multiple-access method is based on a phenomenon of multiple delay capture and is enabled by time reversal technique. Multiple delay capture is a random multiple-access method that can be viewed as a time-of-arrival (TOA) division multiple-access. When received signals are of low duty cycle, the chance...
This paper presents a low-complexity time reversal technique as an enhancement for the ultra-wideband (UWB) communication system over ISI channels, time reversal takes advantage of rich channel impulse response (CIR) to achieve signal focusing in both time domain and spatial domain. But implementing time reversal for UWB applications is extremely challenging. Aiming at designing a practical low-complexity...
