    Error performance of multi-branch dual-hop PF cooperative systems by Guangqiu LI, Jiayun DONG, Tao JIANG

    Published 2016-09-01
    “…Design of multi-branch dual-hop phase-only forward(PF)cooperative systems with continuous phase frequency shift keying(CPFSK)modulation needs to determine the number of branch and modulation index.The usual solution of determining the above parameters is the time-consuming and inefficient computer simulation.An efficient solution of determining these parameters is theoretical analysis method.Semi-analytical expressions for the average bit error rate(ABER)of multi-branch dual-hop PF cooperative systems in conjunction with discrimination detection CPFSK over time-selective Rayleigh fading channels was presented.Two cases with and without antenna selection at the relays and maximum-ratio combining(MRC)receive diversity at the destination were considered.The simulation results show that numerical calculation results and simulation results for the ABERs of PF,discrimination detection,CPFSK cooperative systems are consistent and show that the above ABER theory results of CPFSK cooperative systems can be used to design PF cooperative systems.…”

    STOCHASTIC APPROACH FOR EVALUATION OF RELIABILITY AND RESIDUAL LIFE OF TRANSPORT STRUCTURES by U. N. Rabtsau

    Published 2014-10-01
    “…Such approach for operated structures looks rather ivory-towered because the actual transport loads have a large statistical dispersion, they are characterized by periodicity, dynamic character, they can criss-cross structures and change in time as in short- so in long term prospects as well.Introduction of СТБ ISO 2394-2007 “Reliability of construction structures” on the territory of Belarus has provided an opportunity to pass from deterministic approach on evaluation of reliability and technical state of operated structures that considers virtual impact of substitute design loading on a real structure to probability approach that considers impacts of actual loadings in specific period of time and which can be determined with the help of experiments. Application of reliability parameter as a criterion of transport structure residual life which is determined with the help of probability method will make it possible to improve significantly the evaluation accuracy due mathematical precise accounting of peculiar features pertaining to actual impacts on specific transport structure and thus it will bring criteria for evaluation of transport structure residual life in accordance with the world development level of construction science and technology.…”
