Research on low complexity decoding for SCMA based on serial strategies of variable node
Published 2017-09-01“…Sparse code multiple access technology,as a competitive non orthogonal multiple access scheme for the fifth generation wireless communication network,has a broad application prospect.However,current SCMA uplink use the flooding scheme of message passing algorithm for decoding,both the detection complexity and convergence properties are not ideal.A serial message passing algorithm which changed the information updating strategy was proposed,which performed message processing and deliveried according to the order of the variable nodes.Each of variable node simultaneously performed the reception of the verification message and the transmission of the variable message.The theoretical and simulation results show that the proposed algorithm not only maintains good performance,but also has low decoding complexity.…”

Blind recognition of STBC based on higher-order cumulants
Published 2016-05-01“…Aiming at the problems for blind recognition of space-time block code(STBC)in MIMO communication sys-tems,a method was exploited based on higher-order cumulants of received signals.Firstly,the model of received signals was given and the fourth-order cumulants of the received signals in multiple input single output(MISO)systems was ob-tained.Secondly,using the characteristics of coding matrix,it was proved that the fourth-order cumulants in different de-lay vectors presented non-null value that depended on the STBC sat the transmitter side.Finally,a classifier for the STBC was presented based on the Euclid distance between the experimental values of fourth-order cumulants and the theoretical ones.Simulations show that the method performs well even for low signal to noise ratio.…”

Performance analysis and optimization of cooperative spectrum sensing for maximizing secondary throughput
Published 2011-01-01“…The relationship among SU,detection threshold,bandwidth,spectrum utilization and secondary throughput in cognitive radio networks was analyzed,which indicates the lower false alarm probability,higher spectrum utilization and larger secondary throughput with less SU in C-CSS(censoring based cooperative spectrum sensing),besides,the required detection threshold for maximizing the secondary throughput different with the traditional CSS under given SU number and the objective demand.Based on the NP criticism,an optimal cooperative spectrum sensing algorithm for maximizing the secondary throughput was proposed by solving the mathematic model to obtain the optimal party of SU and detection threshold.Theoretical analysis and simulation results show that the maximized secondary throughput achieved by the proposed optimal algorithm,while maintaining the given detection probability.…”

Using idle TDMA slots for retransmitting packets cooperatively in VANET
Published 2015-07-01“…The distributed TDMA approach for VANET dose not take advantage of idle slots,failing to effectively utilize radio resources.A retransmission method for medium access control was proposed for utilizing idle slots.In the method,neighboring nodes utilized idle slots for retransmitting a packet which failed to reach the target receiver.Theoretical analysis and simulation results show that the proposed method significantly increases the probability of successful packet transmission and the network throughput.In addition,a comparison between the proposed method and IEEE 802.11p was presented via extensive simulation,and the results prove that,due to its ability to access channel determinately,the method can disseminate real-time safety information timely and stably.…”

New kind of CD-DCSK chaos shift keying secure communication system
Published 2012-05-01“…As existing chaos keying communication systems had the issues of low data transmission rate and weak system confidentiality,a new kind of chaos shift keying communication system:CD-DCSK(correlation delay-differential chaos shift keying) was presented.At the same time lucubrated and simulated the communication performances of this new system.The theoretical deduction and emulational experimentation analysis verified that CD-DCSK has both merits of high confidentiality of CDSK and low BER of DCSK,and its transmission rate is twice as much as original shift keying schemes.Meanwhile,this new communication scheme perfectly achieved the secrecy transmission of age signal.Therefore,it can be clearly seen that this new system is realizable and has high security.…”
