由于其正交性和几乎恒定的脉冲宽度，改进埃尔米特脉冲 (MHP) 在通过创建多进制或多址并行系统来增强 UWB 通信的数据速率方面表现出了巨大的潜力。然而，脉冲组生成和频移所需的潜在高功耗限制了它们在实践中的使用。在本文中，我们提出了一种新颖的 MHP 集合生成器计算效率模型。与现有模型相比，所提出的模型使得设计高效的MHP发电机组变得可行。利用我们提出的模型以及神经形态电路级实现，我们开发了一种超低功耗架构，用于 sub-GHz (0 - 960 MHz) UWB 通信的 MHP 集生成。数学分析和设计布局仿真的结果说明了所提出的节能 MHP 发电机组设计方案的有效性。
Due to their orthogonality and nearly constant pulse widths, Modified Hermite Pulses (MHPs) have shown a great potential to enhance the data rate of UWB communications by creating M-ary or multiple access parallel systems. However, the potential high power dissipation required by the pulse set generation and the frequency shifting has limited their utilization in practice. In this paper, we propose a novel computation-efficient model for MHP set generators. Compared with existing models, the proposed model has made it feasible to design a power-efficient MHP set generator. Utilizing our proposed model along with neuromorphic circuit level implementations, we have developed an ultra-low power architecture for MHP set generation for sub-GHz (0 - 960 MHz) UWB communications. Results from both the mathematical analysis and the design layout simulations illustrate the effectiveness of the proposed scheme for the design of a power-efficient MHP set generator.
