    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.…”

    Large-scale terminal access algorithm based on slot ALOHA and adaptive access class barring by Zhenyu ZHU, Xiaorong ZHU, Yan CAI, Hongbo ZHU

    Published 2021-03-01
    “…In order to solve the problem of high collision rate and low timeliness of large-scale terminals access in the Internet of things, a large-scale terminal access algorithm based on slot ALOHA and adaptive access class barring (ACB) was proposed.Firstly, the services were classified based on the data from each terminal by the volume of the services processed and the requirements for delay.For the services that were not time-sensitive and whose effective data portion was less than 1 000 bit, a slot-based ALOHA-based competitive access method was used.ACB-based random access was used for the services that were time-sensitive or whose data portion was greater than 1 000 bit.On this basis, a method was proposed for predicting the access application volume based on the quantitative estimation, and dynamically adjusting the ACB control parameters based on this predicted value.Simulation results show that compared with other existing access algorithms, the proposed algorithm reduces the collision rate and improves the system access success rate under the premise of ensuring the high priority service delay requirements.…”

    Improved particle filtering based algorithm for time delay and symbols joint estimation of PSK signals by Nan XIA, Tian-shuang QIU

    Published 2012-04-01
    “…An adaptive particle filtering algorithm based on resampling was proposed for time delay estimation of PSK signals,which could eliminate the influence of inaccurate posterior possibility distribution caused by the small noise variance and the influence of the increase of estimation error caused by the large noise variance.Taking into account the small time delay estimation being invalid in the existing algorithms,a symbol forward and backward detection technique was applied to achieve random time delay accurate estimation in a symbol period.Otherwise,the carrier frequency offset of the received signal was estimated and compensated.Simulation results verify the novel algorithm can achieve more accurate time delay estimation and lower symbol error rate than the existing algorithm.…”

    Value-difference learning based mMTC devices access algorithm in multi-cell network by Xin LI, Jun SUN

    Published 2022-06-01
    “…In the massive machine type communication scenario of 5G, the access congestion problem of massive machine type communication devices (mMTCD) in multi-cell network is very important.A double deep Q network with value-difference based exploration (VDBE-DDQN) algorithm was proposed.The algorithm focused on the solution that could reduce the collision when a number of mMTCDs accessed to eNB in multi-cell network.The state transition process of the deep reinforcement learning algorithm was modeled as Markov decision process.Furthermore, the algorithm used a double deep Q network to fit the target state-action value function, and it employed an exploration strategy based on value-difference to adapt the change of the environment, which could take advantage of both current conditions and expected future needs.Moreover, each mMTCD updated the probability of exploration according to the difference between the current value function and the next value function estimated by the network, rather than using the same standard to select the best base eNB for the mMTCD.Simulation results show that the proposed algorithm can effectively improve the access success rate of the system.…”
