On the Influence of UMTS Power Control on the Link-Level Error Statistics
نویسندگان
چکیده
This work analyzes the error statistics of the UMTS radio communication at link-level and how it is affected by the power control, by means of measurements and simulations. This information allows to optimize transmission power and to apply cross-layer optimization techniques such as unequal error protection. By use of a high-level Markov model we perform simulations and besides we provide an approximation for it. We show that the outer-loop power control is the only mechanism which effects the link-level error statistics. The measurements are consistent with the simulation results.

A UMTS DL DCH Error Model Based on Measurements in Live Networks
In UMTS system level simulations DCH (Dedicated Channel) error models are used to represent the characteristics of lower layers in order to save simulation time. Usually DCH BLER (Block Error Ratio) statistics are taken from link level simulations or only certain fixed values for DCH BLER are used for system level simulations. In this paper we present measurements of UMTS DL(Down Link) DCH erro...

Particularly in wireless mobile communications, link errors severely affect the quality of the services due to the high error probability and the specific error characteristics (burst errors) in the radio access part of the network. In this thesis it is shown that a thorough analysis and the appropriate modeling of the radiolink error behaviour is essential not only to evaluate and optimize the...
متن کاملA Novel Controller Based on Single-Phase Instantaneous p-q Power Theory for a Cascaded PWM Transformer-less STATCOM for Voltage Regulation
In this paper, dynamic performance of a transformerless cascaded PWM static synchronous shunt compensator (STATCOM) based on a novel control scheme is investigated for bus voltage regulation in a 6.6kV distribution system. The transformerless STATCOM consists of a thirteen-level cascaded H-bridge inverter, in which each voltage source H-bridge inverter should be equipped with a floating and iso...

متن کاملDowlink Soft Handover Gain in Umts Networks under Different Power Control Conditions
In this paper, the downlink soft handover gain is analysed in UMTS networks under three different power control situations: without power control, with perfect power control and with imperfect power control. The results show that although power control in the downlink direction is not as crucial as it in the uplink direction, it does have a significant influence on the downlink soft handover ga...
