An Impulse Ultra-wideband System Capable of Concurrent Transmission and Reception, Part I: Requirements and Innovations

This paper presents a novel ultra-wideband (UWB) system for low power, long range, mid to high data rate mesh networking applications. Combined with the complementary code division multiplexing modulation and the multicode interleaved direct sequence spread spectrum techniques, the system aims to achieve interference resistance, coexistence with legacy systems, and robust performance in hostile multipath environments. The unique feature of the system is the support for concurrent transmission and reception, which will enable a medium access control mechanism with cut-through routing to be developed for high-throughput UWB mesh networks. It is concluded that this new UWB system represents a fundamental advance in UWB technology
