Abstract :
Much attention has been paid to a new form of spread spectrum technique called the ultra wideband impulse radio (UWB-IR) system for future high speed wireless communication services. We present an M-ary scheme that is effective to reduce interference of UWB systems to existing radio systems. The paper presents both theoretic analysis and BER-based computer simulation evaluations of the proposed scheme and shows that the proposed system can overperform the conventional UWB system.
