Active remote sensing of atmospheric XCO2 has several advantages over existing passive remote sensors, including global coverage, a smaller footprint, improved penetration of aerosols, and night observation capabilities. China is planning to launch a multi-functional atmospheric observation satellite equipped with a CO2-IPDA (integrated path differential absorption Lidar) to measure columnar co...

Industrial plants are heterogeneous networks with different computation and communication capabilities along with different security properties. The optimal operation of a plant requires a balance between communication capabilities and security features. A secure communication data flow with high latency and low bandwidth does not provide the required efficiency in a plant. Therefore, we focus ...

In recent years, with the rapid development of wireless communication, the traditional cellular with isomorphic and regular structure has been unable to meet the increasing number of users and business needs involving data of big volume. The trend is evolving into Ultra Dense Network (UDN) architecture which is covered by cellular of irregular complex structure. In UDN, the spatial distribution...

Abstruct-This paper presents a random spreading code assignment scheme for enhancing channel efficiency in centralized DS-SS packet radio networks which employ a multiple-capture receiver for each code channel. Compared to the common code case, this approach requires modest increase in receiver complexity, but the number of distinct spreading codes being used is considerably less than the numbe...

Michele Zorzi, Member, IEEE Abstract—In this paper, we provide a general analytical framework for the computation of the interference statistics in mobile radio cellular systems. This approach, which takes into account log-normal shadowing, distance path loss, best cell site selection and power control based on signal strength, applies to various cellular environments, including narrowband syst...

In current wireless LANs multiple kinds of losses occur (i.e., channel errors, collisions, interference). In this paper we examine the extent to which loss differentiation based physical layer transmission bit–rate and contention window adaptation aids in improving network performance. We show that loss differentiation can have a positive impact on performance, especially in low contention scen...

Electrocardiogram (ECG) holds high significance in medical diagnostics. Cardiologists consider it as an enduring tool and thus the improvement of the diagnostic quality the signal for various recognitions in different environments become a challenge. The signal acquisition is susceptible to the interference from physiological as well as environmental sources. Foetal ECG provides vital informati...

in this paper, behavior of teleoperation systems with modeling error and delay time error in smith predictor is discussed. in teleoperation systems, modeling error is inevitable. this paper discusses stability of teleoperation systems with modeling error. first, error of delay time in teleoperation systems by using of internet as communication channel is considered and the performance of smith ...
