In terms of second-order nonlinearity, nonlinear distortion in an EAM-based IMDD OFDM system is deterministically modeled as subcarrier-to-subcarrier intermixing interference (SSII), such that DSP-based nonlinear compensation can be provided by decision-aided SSII cancellation at the receiver. The effectiveness of SSII cancellation heavily relies on the accuracy of SSII calculation, which is determined...
This paper takes the online automobile brand community as an example, importing ‘interactivity’, the concept of sociology, into online brand community study. It follows the logical way as ‘How does interactivity embody among the online communities → How about its deepening process? →What the results of interactivity will be?’, that is, ‘formation of the relationship (Interaction) — deepening of the...
Electrocardiogram is previously verified as a new biometric for human identification. However, it is uncertain if changes of cardiovascular conditions may cause any difference. The research investigates if cardiovascular conditions may impact ECG biometrics. A longitudinal and cross-section investigation is applied on peritoneal dialysis patients. Our results show that ECG is still able to identify...
Because of the enormous growth in the number of peer-to-peer (P2P) applications, P2P traffic now constitutes a substantial proportion of Internet traffic. The ability to accurately identify different P2P applications from the network traffic is essential for managing a number of network traffic issues, such as service differentiation and capacity planning. However, modern P2P applications often use...
