Pilot Position Optimization Design of WLAN System Based on Experiment
Published 2015-08-01“…Considering the frame structure of IEEE 802.11ac with “leading preamble plus comb-like pilot”,the performance evaluation formula of the correction scheme based on maximum likelihood estimation was derived,according to which the effect of pilot location,channel fading and subcarrier correlation was studied.Furthermore,a signalling exchange method was proposed,which ensured pilot position synchronization on both end,and a low complexity algorithm of pilot optimization according to the frequency channel amplitude information.In this way,the pilot overhead can be reduced without loss of correction performance.The experiment and simulation result shows that for ideal Rayleigh channel data,correction performance improves by 1.85 dB and 7.15 dB for unknown channel amplitude information in frequency domain and known cases respectively.For field experiment channel data,correction performance improves by 1.67 dB and 2.68 dB respectively.…”

Multicast resource allocation scheme considering source-coding characteristic in OFDM systems
Published 2010-01-01“…Aiming to solve the problem that unicast or conventional multicast was incapable of make full use of the opening for wireless propagation in orthogonal frequency division multiplexing(OFDM) systems,a resource allocation scheme involving several multicast groups was proposed to maintain proportional fairness among groups.The proposed scheme consisted of subcarrier assignment algorithm and power allocation algorithm.The former was achieved by modi-fying the existing unicast subcarrier assignment algorithm,whilst optimal power allocation on condition that subcarrier assignment was determined was reached by the latter based on theoretically derived non-linear equations.Simulation re-sults show that the proposed scheme can ensure perfect fairness among different multicast groups,and remarkably out-performs conventional multicast in terms of rate-sum capacity.Combined with the low complexity,it is suitable for the application to voice/video multicast in actual wireless systems.…”

Improved SOR signal detection algorithm in massive MIMO-TRDMA systems
Published 2021-10-01“…In the massive multi-input multi-output time-reversal division multiple access (MIMO-TRDMA) systems, the traditional linear minimum mean square error (MMSE) algorithm achieved approximately the best performance.However, the matrix inversion of the MMSE algorithm was too complicated to ensure real-time processing of signal detection.To solve this problem, an improved successive over-relaxation (SOR) signal detection optimization algorithm was proposed.The proposed algorithm reasonably upgraded the solution of linear equations to prevent the complicated calculation of matrix inversion.Meanwhile, the steepest descent idea was used to provide an effective search direction for the SOR signal detection algorithm, achieving a rapid convergence rate and stronger inspection performance.The simulation results show that the proposed algorithm has the similar best performance with fewer update times compared with the traditional MMSE algorithm, and the calculation complexity is reduced from O(M<sup>3</sup>)to O(<sup>2</sup>).…”

Multi-dimensional secure query scheme for fog-enhanced IIoT
Published 2020-08-01“…In view of the fact that most of the existing range query schemes for fog-enhanced IoT cannot achieve both multi-dimensional query and privacy protection,a privacy-preserving multi-dimensional secure query scheme for fog-enhanced IIoT was proposed.Firstly,the multiple ranges to be queried were mapped into a certain query matrix.Then,auxiliary vectors were constructed to decompose the query matrix,and then the auxiliary vector was processed by BGN homomorphic encryption to form a query trapdoor.Finally,with the homomorphic computation utilized by an IoT device terminal,the query trapdoor could be matched to its sensor data.Spatial complexity could be effectively reduced with the used specific auxiliary vectors.The confidentiality of sensor data could be ensured and the privacy of user’s query mode could be protected by the homomorphic encryption property.Experiments results show that the computational and communication costs are relatively low.…”
