Hard-input-hard-output capacity analysis of UWB BPSK systems with timing errors [PDF]

open access: yes, 2012
The hard-input-hard-output capacity of a binary phase-shift keying (BPSK) ultrawideband system is analyzed for both additive white Gaussian noise and multipath fading channels with timing errors.

Improved training sequence structure and timing and frequency synchronization algorithm for OFDM system

open access: yesDianzi Jishu Yingyong, 2019
An improved timing and frequency synchronization algorithm based on Zadoff-Chu(ZC) sequence for OFDM system is proposed. The algorithm constructs a training sequence with conjugate repetition relationship. Firstly, the timing synchronization is completed

Saccade-related modulations of neuronal excitability support synchrony of visually elicited spikes [PDF]

open access: yes, 2011
During natural vision, primates perform frequent saccadic eye movements, allowing only a narrow time window for processing the visual information at each location.

Synchronization of a WDM Packet-Switched Slotted Ring [PDF]

open access: yes, 2007
In this paper, we present two different strategies of slot synchronization in wavelength-division-multiplexing (WDM) packet-switched slotted-ring networks.

Desynchronization: Synthesis of asynchronous circuits from synchronous specifications [PDF]

open access: yes, 2006
Asynchronous implementation techniques, which measure logic delays at run time and activate registers accordingly, are inherently more robust than their synchronous counterparts, which estimate worst-case delays at design time, and constrain the clock ...

Multimode coordinated multipoint transmission with nonideal timing synchronization

open access: yesTongxin xuebao, 2016
Against the negative impact of non-ideal timing synchronization on the coordinated multipoint (CoMP) trans-mission, a multimode algorithm was proposed.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.
