    Joint resampling algorithm for parallel dual feedback time-frequency domain symbol timing recovery by Peixin ZHANG, Nan ZHANG, Daqing WANG, Tong WU, Zhe LI, Fengkui GONG

    Published 2023-04-01
    “…Aiming at the problem that it is difficult for existing implementation algorithms of symbol timing recovery to give full consideration to high convergence accuracy and the robustness to resist timing deviation, a high-speed parallel symbol timing recovery algorithm with resampling was proposed.The timing frequency offset and timing phase offset were corrected by using double feedback loops.In the design of parallel resampling, the implementation of parallel numerically controlled oscillators and the use of enable signals sorting and shift registers to implement data reordering were proposed.When designing the timing recovery loop, the parallel implementation structure of the O&M timing error estimation algorithm was analyzed and deduced, and the design method and implementation structure of the loop correction were proposed based on the analysis of the timing phase/frequency offset correction principle.The FPGA test results show that the proposed algorithm can realize the symbol timing recovery of 64APSK modulated signals with arbitrary multiple symbol rate between 4 and 16 times, and the error vector magnitude (EVM) with the ideal signal is within 4%, which meets the requirements of broadband satellite communication.…”

    Optimal Relay Selection Strategy in Cognitive Cooperative Relaying Network by Yinshan Liu, Xiaofeng Zhong, Jing Wang

    Published 2015-11-01
    “…Cognitive cooperative relaying communication significantly improves the performance of wireless communication networks and spectral efficiency.Optimal relay selection problem,which characterize the desired tradeoff between the probing cost for establishing cooperative transmission and hence higher reward via cooperative diversity,is a hard issue when the number of relay nodes is large.Optimal relay selection strategy was established by using optimal stopping theory with a finite horizon.Furthermore,a pure SNR(signal-to-noise ratio)threshold structure was exhibited.Theoretical analysis and numerical results indicate that proposed optimal relay selection strategy is effective in reducing the number of probing candidate relays and improving the reward of source.…”
