Robustness analysis method is proposed for rotorcraft pilot coupling with helicopter flight control system in loop. Combining with the lateral identification model of BO-105 helicopter, McRuer's pilot model, and the designed stability augmentation system, frequency domain model is established for rotorcraft pilot coupling analysis. μ analysis method and performance specifications in ADS-33E are adopted...
The widespread deployment of optical interconnects in data centers has renewed the interest in multimode fiber communications. Due to the complexity of modern transmission techniques, performance analysis relies on numerical simulations that require an accurate channel model to reflect reality with the needed precision. As there is no standard model for channel simulation, we investigate a deterministic,...
New designs for a 1 times 4 and a 1 times 8 CWDM multiplexers based on cascaded groups of series coupled ring resonators are presented. Compared to other integrated optical alternatives such as MMI phasars, cascaded Mach-Zehnder interferometers and cascaded AWG, the proposed circuits offer superior performance in their very sharp roll-off factor that exceeds 0.75, their reduced crosstalk level that...
Current mode (CM) scheme provides suitable alternative for the high speed on-chip interconnect signaling. This paper presents a energy-delay optimization methodology for the current-mode (CM) signaling scheme. Optimization for the CM circuits for on-chip interconnects requires a joint optimization of driver and receiver device sizes, as their parameters which affect the energy-delay performance depend...
Channel mismatch, including amplitude and phase mismatch, has severely affected the performance of space-time adaptive processing (STAP). In order to ascertain the specification of the effects on STAP, theory analysis of relation between clutter covariance matrix (CCM) with and without channel mismatch is done based on the model provided by literature, and the effect to signal is also analyzed. In...
The next generation Internet will be highly diversified in both underlying networking technologies and supported networking applications. The diversified Internet architecture requires effective collaboration among heterogeneous network domains to support various application requirements. One of the challenges to achieve this objective lies in enabling network domain collaboration and network-application...
