Detection of High Baud-Rate Signals With Pattern ... - IEEE Xplore
2017年4月6日 · To improve the performance-complexity trade-offs of this approach, we model the PDD degraded signal as drawn from a hidden Markov model (HMM). Detection of the transmitted symbols given the received signal is performed by finding the HMM state sequence that emits the received signal with maximum a posteriori probability (MAP).
Harvard ManageMentor - Aramco Life
2021年2月24日 · More than 21,000 Aramco employees have completed over 40,000 learning modules on Harvard ManageMentor (HMM), the online education platform offered by Harvard Business Publishing. “Use of HMM has been very impressive,” said Colin Sloman, director of the Management and Professional Development Department (M&PDD).
Detection of High Baud-Rate Signals With Pattern Dependent …
In high baud-rate systems, the bandwidth limitations and nonlinearities of drive amplifiers and optical modulators can introduce pattern dependent distortion (PDD) that limits system performance. One solution entails detecting the transmitted symbols with the aid of a look-up table (LUT) containing prototypes of the PDD degraded signal.

2019年12月24日 · A Hidden Markov Model based Path Association(HMM-PA) framework is presented to jointly analyze image path and geospatial path. In addition, according to our research scenario, we manually annotate path description on two large-scale public re-ID datasets, termed as Duke-PDD and Market-PDD.
本文对2 种常用的测试波形:HMM 波形和TLP波形所对应的ESD防护器件的检测方法进行了说明。 通过对同一型号瞬态电压抑制器进行测试,对比2种检测波形的测试结果,分析了不同方法在评估ESD防护器件性能方面各自的优缺点。 HMM 波形的测试方法有2种:基于IEC61000-4-2 的HMM 测试和基于50 Ω 的HMM测试[12]。 这 2种测试所采用的波形模块电路结构不同,相同点在于当被测器件(DUT )为2 Ω电阻时,电流探头所测的DUT端的电流波形都符合IEC61000-4-2 标准中规定 …
