    CC-MRSJ:Cache Conscious Star Join Algorithm on Hadoop Platform by Guoliang Zhou, Yongli Zhu, Guilan Wang

    Published 2013-10-01
    “…A cache-conscious MapReduce star join algorithm was presented,each column of fact table was separately stored,and dimension table was divided into several column families according to dimension hierarchy.Fact table foreign key column and corresponding dimension table was co-location storage,thus reducing data movement in the join process.CC-MRSJ consists of two phases:firstly each foreign key column and the corresponding dimension table were joined; then the intermediate results were joined and random accessed measure columns,and so got the final result.CC-MRSJ read only the data needed,and cache utilization is high,so it has good cache conscious feature; it also takes advantage of late materialization,avoiding unnecessary data access and movement.CC-MRSJ has higher performance comparing to hive system based on SSB datasets.…”

    Sparse adaptive constant blind equalization algorithm for sparse multipath channel by Si-yang MA, Hua PENG, Bin WANG

    Published 2017-01-01
    “…In order to improve the convergence rate of the blind equalizer for sparse multipath channel,a novel blind equalization approach called l<sub>0</sub>-norm constraint proportionate normalized least mean square constant algorithm was proposed for M-order phase-shift keying (MPSK) signal.Based on the constant modulus characteristics of MPSK signal and the sparse property of equalizer,a new blind equalization cost function with the l<sub>0</sub>-norm penalty on the equalizer tap coefficients was firstly constructed.Then the update formula of the tap coefficients was derived according to the gradient descent algorithm.Moreover,the iteration step was updated by drawing upon the normalized proportionate factor.The algorithm not only assigned step sizes proportionate to the magnitude of the current individual tap weights,but also attracted the inactive taps to zero adaptively.Theoretical analysis and simulation results show that the proposed algorithm outperforms the existing blind equalization algorithms for sparse channel in reducing ISI and improving convergence rate.…”

    Algorithm based on randomly assigning filters to reduce PAPR in GFDM system by Miao ZHANG, Xianzhong XIE, Lei WU, Weijia LEI

    Published 2016-09-01
    “…As an alternative of the fifth generation mobile communication system waveforms,generalized frequency division multiplexing(GFDM)which has more advantages over OFDM has been trusted into the limelight.Nevertheless,GFDM still suffers from a high peak to average power ratio(PAPR).Considering that different filters have their own phase-frequency characteristics,a new algorithm based on randomly assigning filters to reduce PAPR in GFDM(RAF-GFDM)was proposed.According to the feature of GFDM system that the filter structure could be selected flexibly,different filters were assigned to subcarriers randomly to adjust the phase congruency due to signals superimposition.Additionally,this method can suppress PAPR effectively without causing signal distortion.Theoretical analysis and simulation results demonstrate that the proposed algorithm does not bring additional calculation costs while reducing PAPR and almost has no effect on the bit error rate(BER),and it may provide a higher application value.…”
