Transmitting digital information using ultra-short pulses, Impulse Radio (IR) has received increasing interest for Multiple Access (MA). Analog IRMA utilizes pulse-position modulation (PPM) and random time-hopping codes to mitigate inter-symbol interference (ISI) and suppress multiuser interference (MUI) statistically. We develop an all-digital IRMA scheme that relies on block-spreading and judiciously designed transceiver pairs to eliminate MUI deterministically, and regardless of ISI multipath effects.
