用于通信的超宽带（UWB）无线电具有若干挑战。从物理层的角度来看，信令技术应该被优化设计为与底层硬件协同工作，以实现最大性能。在本文中，我们提出了一个变种的脉冲位置调制（PPM）的物理层信令，它可以实现原始比特率超过150 Mbps的低复杂度在内部开发的脉冲无线电UWB平台。信令系统被优化以在低复杂度硬件和监管机构的实际约束下最大化比特率。我们提出了一种检测器，并推导出其理论性能界限，并在仿真中的误符号率（SER）的性能进行比较。提出了对信令的修改，其可以将范围增加4倍，同时略微增加硬件复杂度。检测器的这种修改和比较研究所提出的UWB物理层信令方案的误符号率方面的性能进行了讨论。
Ultra wideband (UWB) radio for communication has several challenges. From the physical layer perspective, a signaling technique should be optimally designed to work in synergy with the underneath hardware to achieve maximum performance. In this paper, we propose a variant of pulse position modulation (PPM) for physical layer signaling, which can achieve raw bitrate in excess of 150 Mbps on a low complexity in-house developed impulse radio UWB platform. The signaling system is optimized to maximize bitrate under practical constraints of low complexity hardware and regulatory bodies. We propose a detector and derive its theoretical performance bounds and compare the performance in simulation in terms of symbol error rates (SER). Modifications to the signaling, which can increase the range by 4 times with a slight increase in hardware complexity, is proposed. Detectors for this modification and a comparative study of the performance of the proposed UWB physical layer signaling schemes in terms of symbol error rates are discussed.
