    Low complexity algorithm for PAPR reduction in GFDM system by Jianhui CAI, Guangqiu LI, Jingjie SHEN

    Published 2021-04-01
    “…In order to reduce the peak-to-average power ratio (PAPR) and the implementation complexity of generalized frequency division multiplexing (GFDM) system, the TSLM algorithm based on T-transform and selective mapping (SLM) was proposed.The design idea of the TSLM algorithm was to use the SLM algorithm to increase the number of GFDM time-domain alternative signals to reduce the PAPR, and to use the T-transform to realize the joint operation of the Walsh-Hadamard transform and the inverse discrete Fourier transform to reduce the complexity of the system.To further reduce the PAPR of the GFDM system, the TCSLM algorithm combining the TSLM algorithm and the conversion vector (CV) was proposed, and the CV vector was used to increase the number of GFDM time-domain alternative signals.The results show that when the number of subcarriers is 64, the number of sub symbols is 3 and the number of phase sequences is 2, compared with the SLM algorithm, the implementation complexity of the TSLM and TCSLM algorithm decreases by about 21.9% and 60.9%, respectively.When the complementary cumulative distribution function (CCDF) is 10<sup>-3</sup>, the PAPR of the TSLM and TCSLM algorithm decreases by about 0.6 dB and 1 dB, respectively.The error performance of the TSLM and the TCSLM algorithm is improved by about 2 dB when the bit error rate is 10<sup>-3</sup>.…”

    Low-complexity and QoS-awared scheduling algorithm for LTE by Fei-long ZHAO

    Published 2013-12-01
    “…Based on the relaxation based linearization principle and the greedy algorithm,a scheduling algorithm named QPF was designed with low complexity and full QoS-awared.It is divided into two parts:time and frequency domain,which can allocate all resources at once according to two service types:GBR and Non-GBR service.By this way the computation complexity decreases from O(M<sup>N</sup>)to O(M lb N).The proposed algorithm has a balanced performance in si-mulation,which can get 10% improvement in some dimensions compared with the references with high load and provide a nice trade-off between the performance and complexity.…”

    Fast and low-complexity video down-sizing transcoder by Zhuo-yi LV, Ke-bin JIA, Wan-chi WIU

    Published 2012-01-01
    “…An efficient mode decision scheme for down-sizing video transcoding in H.264 using support vector machines (SVM)was proposed.In order to reduce the high computationa complexity of using conventional mode decision in the H.264 re-encoder,the proposed scheme used SVM to exploit the correlation between coding information extracted from the input high-resolution bit-stream and the coding modes of macro-blocks in down-sized video frames.The key techniques of training and predicting SVM including feature vector and kernel function were studied and then the SVM model was trained.After the hierarchical SVM classifier,improbable modes were eliminated and only a small number of candidate modes were carried out using the RDO operations.Hence,remarkable computing time could be saved,up to 67.31%,while maintaining nearly the same quality of the transcoded pictures.…”
