Statistical Properties of Double Hoyt Fading With Applications to the Performance Analysis of Wireless Communication Systems
2018
In this paper, we investigate the statistical properties of double Hoyt fading channels, where the overall received signal is determined by the product of two statistically independent but not necessarily identically distributed single Hoyt processes. Finite-range integral expressions are first derived for the probability density function (PDF), cumulative distribution function (CDF), level-crossing rate (LCR), and average duration of fades of the envelope fading process. A closed-form approximate solution is also deduced for the LCR by making use of the Laplace approximation theorem. Applying the derived PDF of the double Hoyt channel, we then provide analytical expressions for the average…
Performance Analysis of Cooperative V2V and V2I Communications Under Correlated Fading
2019
Cooperative vehicular networks will play a vital role in the coming years to implement various intelligent transportation-related applications. Both vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications will be needed to reliably disseminate information in a vehicular network. In this regard, a roadside unit (RSU) equipped with multiple antennas can improve the network capacity. While the traditional approaches assume antennas to experience independent fading, we consider a more practical uplink scenario where antennas at the RSU experience correlated fading. In particular, we evaluate the packet error probability for two renowned antenna correlation models, i.e., cons…
Connected vehicles : can V2V communication and internet connectivity improve safety?
2016
This study explores the possibilities of V2V communication on vehicles. Starting with a broad overview of the history of vehicle safety, leading up to current safety technologies and then adding digitalization. Many parts of the everyday life became digital in recent years and the most used transportation device–the car–is to some extend already part of it. The latest studies on the subject will be examined and how the car manufacturers picture the near future of cars that are connected. The possibilities are nearly endless; a car could be aware of an upcoming obstacle, also infrastructure such as traffic lights could send information to approaching cars. In addition, the regular Internet c…
Real-time smoothing of car-following data through sensor-fusion techniques
2011
Abstract Observation of vehicles kinematics is an important task for many applications in ITS (Intelligent Transportation Systems). It is at the base of both theoretical analyses and application developments, especially in case of positioning and tracing/tracking of vehicles, car-following analyses and models, navigation and other ATIS (Advanced Traveller Information Systems), ACC (Adaptive Cruise Control) systems, CAS and CWS (Collision Avoidance Systems and Collision Warning Systems) and other ADAS (Advanced Driving Assistance Systems). Modern technologies supply low-cost devices able to collect time series of kinematic and positioning data with medium to very high frequency. Even more da…
Runas valodas noteikšana
2021
Dabiskās valodas apstrādes jomā valodas noteikšana vai valodas uzminēšana nozīme noteikt satura dabisko valodu. Runas valodas noteikšanas uzdevums ir noteikt runas audio ieraksta valodu. Runas valodas noteikšanai ir daudz pielietojumu. Tas ir svarīgs pirmais solis vairākās runas apstrādes sistēmās. Ja valoda tiek identificēta nepareizi, jebkura turpmāka apstrāde sniegs kļūdainus rezultātus. Tas ir īpaši svarīgi daudzvalodu kopienās, kur daudzas vairākas valodas tiek izmantotas salīdzinoši bieži. Šī darba mērķis ir izpētīt runājamās valodas noteikšanas metodes, koncentrējoties uz 3 Latvijā runājamām valodām: latviešu, krievu, angļu.
