Estimation scheme for parameters of wireless channel model in OFDM communication systems by WANG Yong, GE Jian-hua, WU Xiao-li

“…The conventional channel estimator in OFDM system was designed to cope with the worst-case channel condi-tion,thus performance degradation can be induced due to the imperfect channel estimation.Though wiener filter based on the minimum mean-squared error（MMSE） is the optimal linear estimator,it requires the prior information of transmis-sion channel.In order to select the near optimal prestored channel interpolation filter coefficients,three channel parame-ters detecting methods including maximum multipath delay,Doppler frequency and SNR based on the time and fre-quency correlation functions of the channel,the Euclidean distance of hard-decision in pilots position respectively,were proposed.The method proposed with low complexity allows an efficient implementation for adaptive channel estimation algorithm as well as multi-user OFDM systems.…”

Advantage estimator based on importance sampling by Quan LIU, Yubin JIANG, Zhihui HU

“…In continuous action tasks,deep reinforcement learning usually uses Gaussian distribution as a policy function.Aiming at the problem that the Gaussian distribution policy function slows down due to the clipped action,an importance sampling advantage estimator was proposed.Based on the general advantage estimator,an importance sampling mechanism was introduced by the estimator to improve the convergence speed of the algorithm and correct the deviation of the value function caused by calculating the target strategy and action strategy ratio of the boundary action.In addition,the L parameter was introduced by ISAE which improved the reliability of the sample and limited the stability of the network parameters by limiting the range of the importance sampling rate.In order to verify the effectiveness of the ISAE,applying it to proximal policy optimization and comparing it with other algorithms on the MuJoCo platform.Experimental results show that ISAE has a faster convergence rate.…”

Simulated annealing on uncorrelated energy landscapes by Ben Goertzel, Malwane Ananda

“…A recurrence relation expressing the effectiveness of the algorithm in terms of the function G is derived. Surprising numerical results are obtained, to the effect that for certain parametrized families of functions {Gc,   c∈R}, where c represents the steepness of the curve G′(u), the effectiveness of simulated annealing increases steadily with c These results suggest that on the average annealing is effective whenever most points have very small objective function values, but a few points have very large objective function values.…”

Analysis on traveling time of Internet by LI Chao, ZHAO Hai, ZHANG Xin, YUAN Shao-qian

“…Based on the giant data samples authorized by CAIDA,it found that the Internet traveling time was typically distributed by multi-modal and heavy-tailed when the Internet traveling time was statistically analyzed.Furthermore,a research on the relationship between the traveling diameter and the traveling time from the whole and local data samples supposed that link delay was the leading cause for the great variance of the traveling time,and a revising algorithm was proposed to process the raw data samples to obtain link delay.The statistical analysis of link delay presented that the ratio of the biggest link delay to the traveling time in more than 90% of paths was over 1/4.Then a definition of dominant delay was put forward.The traveling time is affected greatly by dominant delay,which makes the similar diameter’s traveling time distinct.…”

Quantum Key Relay Scheme Based on Trusted Control Center by Shaosheng Jiang, Ruinan Chi, Xiaojun Wen

“…A transmit quantum key relay scheme based on trusted control center and trusted quantum relay server was proposed.The quantum key one-time pad encryption algorithm was used in the design of trusted relay protocol.Upon the establishment of trusted relay network,the trusted control center was used to ensure the credibility and security of access relay,and the user's IP address was hidden in the quantum information data that had been encrypted only for the legal user to decrypt and transmit credible information.The security analysis shows,users who do not connect with the quantum channel can still use the trusted relay network to transmit quantum key securely in a long-distance transmission while attackers can not obtain useful quantum key information from the network.…”
