In this paper, the authors investigate spectrum sharing and multiple access problems for the high-rate Ultra-WideBand (UWB) systems. Based on the use of the Linear Pre-coded Orthogonal Frequency Division Multiplexing (LP-OFDM) proposed as an evolution of the well known Multi-Band OFDM (MB-OFDM) solution supported by the WiMedia Alliance for future high-rate UWB systems, the objective of this paper is to study a multiuser optimization spectrum sharing scheme for LPOFDM UWB systems. This optimization study leads to a novel multiple access solution for the high-rate UWB systems. Simulation results demonstrate the efficiency of the use of the LP-OFDM transmission technique in the multiuser spectrum sharing scheme.
