1. Applications of Resource Optimization in Wireless Networks
Sammanfattning : The demand for wireless communications is increasing every year, but the available resources are not increasing at the same rate. It is very important that the radio resources are used in an efficient way allowing the networks to support as many users as possible. LÄS MER
2. Optimization Models and Methods for Telecommunication Networks using OSPF
Sammanfattning : The routing in OSPF Telecommunication networks is determined by computing shortest paths with respect to link weights set by the network operator. All shortest paths to a destination are used by the routers when traffic is routed, and the routers split the traffic evenly when alternative shortest paths exist. LÄS MER
3. Radio Frequency Power Amplifiers : Behavioral Modeling, Parameter Reduction, and Digital Predistortion
Sammanfattning : This work considers behavioral modeling, parameter-reduction, and digital predistortion of radio frequency power amplifiers. Due to the use of modern digital modulation methods, contemporary power amplifiers are frequently subjected to signals characterized by considerable bandwidths and fast changing envelopes. LÄS MER
4. Cooperative Variable Speed Limit Systems : Modeling and Evaluation using Microscopic Traffic Simulation
Sammanfattning : During the last decades the road traffic has increased tremendously leading to congestion, safety issues and increased environmental impacts. As a result, many countries are continuously trying to find improvements and new solutions to solve these issues. LÄS MER
