Abstract A solution of Ultra-Wide Band（UWB） communication systems based on Cyclic Prefix and Pulse Modulations （UWB-CP/PM） and its corresponding signal processing algorithms are presented for short-range wireless networks in this paper. Borrowing the basic idea from the Single-Carrier system with Cyclic Prefix （SC-CP）, an UWB-CP/PM system is capable of elegantly combating multipath interferences by employing transform-domain equalization. Due to pulse modulations, it can significantly simplify its transceiver. By exploiting the property that the pulse repetition period is much larger than the duration of each pulse, it is able to not only ease the requirements on the speed of baseband processing through multi-branch receiving and parallel processing, but also efficiently suppress fading, narrow-band interferences and multiuser interferences by transform-domain signal processing. Simulation results verify the above-mentioned claims.
