摘要：
Ultra-Wideband (UWB) transmission is a promising technology for future high speed wireless communications. RAKE reception is important since it can make use of the rich multipath of UWB systems to improve system performance and capacity. At the same time, much research has been directed towards finding efficient modulation schemes for UWB systems. Recently, biorthogonal pulse position modulation (BPPM), which combines pulse position modulation (PPM) and biorthogonal signals has been proposed for UWB systems. In this paper we study a BPPM modulated TH-UWB system with RAKE reception over block fading channels. The capacity and error rate performance are derived over a multipath fading channel for both the single user and multiple access cases. Numerical results are given to illustrate the theoretical results.
