  1. 26. Framework for Calibration of a Traffic State Space Model

    University essay from Kommunikations- och transportsystem; Tekniska högskolan

    Author : Mats Sandin; Magnus Fransson; [2012]
    Keywords : traffic; framework; calibration; macro traffic model; ensemble kalman filter; cell transmission model;

    Abstract : To evaluate the traffic state over time and space, several models can be used. A typical model for estimating the state of the traffic for a stretch of road or a road network is the cell transmission model, which is a form of state space model. This kind of model typically needs to be calibrated since the different roads have different properties. READ MORE

  3. 27. Computationally Efficient Model for On-Board Simulation of Heavy Duty Diesel Engines

    University essay from Institutionen för systemteknik; Tekniska högskolan

    Author : Per Darnfors; Alfred Johansson; [2012]
    Keywords : Real-time engine model; on-board; driveline prediction; AMT; gear selection;

    Abstract : Simulating the translatory motion of a vehicle during a gear shift gives a good basis to evaluate performance and comfort of a gear shift. This evaluation can be used for gear shifting strategy in an automatic transmission. READ MORE

  4. 28. Hybrid Power Control in Time Division Scheduling Wideband Code Division Multiplex Access

    University essay from KTH/Kommunikationssystem, CoS

    Author : Zhuo Cheng; [2011]
    Keywords : WCDMA; High-Speed Uplink Packet Access; Power Control; unused code GRAKE;

    Abstract : With high date rates using Enhanced Uplink (EUL), a conventional signal to interference ratio (SIR) based power control algorithm may lead to a power rush due to self interference or incompatible SIR target [2]. Time division (TD) scheduling in Wideband Code Division Multiplex Access (WCDMA) is considered to be a key feature in achieving high user data rates. READ MORE

  5. 29. On Models for Interference Calculations between Radio Communication Systems

    University essay from KTH/Signalbehandling

    Author : Fredrik Vihlborg; [2011]
    Keywords : ;

    Abstract : When installing a new radio system, it is of great importance to know that it will not interfere with the already existing systems, and that they can coexist side by side. The problems that will follow if interference occurs, can be of huge magnitude, e.g. radars not working, trains stopping etc. READ MORE

  6. 30. Methods for Path loss Prediction

    University essay from Matematiska och systemtekniska institutionen

    Author : Cem Akkasli; [2009]
    Keywords : path loss; methods; prediction; hata; walfisch; bertoni; large scale; radio transmission; urban; rural; models;

    Abstract : Large scale path loss modeling plays a fundamental role in designing both fixed and mobile radio systems. Predicting the radio coverage area of a system is not done in a standard manner. Wireless systems are expensive systems. READ MORE
