Bare-hand alphabets gesture recognition based on VCM and ROI segmentation
Published 2007-01-01“…A bare-hand gesture location and tracking system with single camera in real-time was introduced.By employing improved difference method,restrictions of hand are used to location region of Interesting(ROI).Then on the basis of relatively satisfied segment result the thesis analyzed and extracted the hand features combined with the improved vector coherence mapping(VCM) whose constraint was enhanced to overcome the illegibility for robust results.Furthermore,a time-correlation forecasting model proved the demand of real-time and the consistency of the results now and before.The experiment results show the system has a high recognition rate up to 99% in different illuminations and backgrounds and has more efficient performance compared with existing other systems.…”

A novel receiver for uplink SCMA system
Published 2017-08-01“…Sparse code multiple access (SCMA) is a type of code domain non-orthogonal multiple access technology,which is regarded as a promising multiple access technology for 5G due to its excellent performance.The uplink SCMA system generally uses a message passing algorithm (MPA) in the receiver.The priori information can be inaccurated to cause an increased detection error.A novel receiver for the uplink SCMA system,called ring-MPA (R-MPA) receiver,was proposed to solve this problem,by using a joint detection process.The proposed R-MPA receiver was compared with the log-MPA receiver and the classic MPA receiver,two state-of-the-art existing schemes.Both theoretical analysis and computer simulation results show that the proposed receiver not only has a superior error performance,but also has a lower implementation complexity than these existing schemes.…”

Impact of overload factor on uplink SCMA system
Published 2018-06-01“…Sparse code multiple access (SCMA) is regarded as a promising multiple access technology for 5G because of its excellent performance.One of the major challenges that 5G networks are facing is the massive connectivity in terms of both data volume and the number of devices,thus SCMA must be capable of coping with transmission overload.Analyzing the performance of the uplink SCMA system in overloading scenarios was focused on.At first,the influence of the overloading factor on the detection and decoding complexities and error performances of the uplink SCMA system were analyzed.Then,by establishing the relationship between the overloading factor and the average sum-rate,the impact of the overloading factor on the transmission rate of the uplink SCMA system was analyzed.Extensive numerical results are provided to verify the accuracy and insights derivable from the analytical results.…”

SCMA codebooks design for Rayleigh fading channel
Published 2022-04-01“…According to the symbol error eate (SER) of the superimposed constellation, the near-optimal space code multiple access (SCMA) codebooks were explored under uplink and downlink Rayleigh fading channels, respectively.A near-optimal codebook design scheme was proposed based on the mathematical model between the superimposed constellation and the SER formula.And the proposed design procedures could be summarized as follows, design the factor graph matrix, match the best codeword pair, and find the optimal angle.Numerical results are provided to demonstrate that the proposed scheme can achieve near-optimal SER performance.…”
