This letter proposes the Pulse-position Multi-pulse Modulation (PMM) with multiple access DTR-UWB systems for the ECC's proposed radiation mask on September 2005 and Japan's radiation mask on March 2006. For the ECC's proposed radiation mask and Japan's radiation mask, the UWB system has to consider the effect from Remote Access Service (RAS) and Radar system between 4.8-5 GHz and 5-6 GHz, respectively. That will limit the bandwidth of the system to just 3.4-4.8 GHz. The simulation results show that the performance of the proposed system is superior to that of the conventional TR-UWB communication system. Moreover, compared to the FCC's system, the proposed PMM DTR-UWB and conventional system have better error performance and higher total throughput at low Eb/N0. So for power limiting system like UWB, ECC's and Japan's systems may become the strong candidates in the UWB communication system.
