Novel direct sequence spread spectrum communication method by Fanglin GU, Jinlin PENG, Yuzhen HUANG, Shengqun CAO, Haitao ZHAO, Jibo WEI

“…In response to the problem of limited performance and low spectral efficiency in complex multipath environments of traditional direct sequence spread spectrum communication, a cyclic prefix (CP) block transmission structure spread spectrum system with a time-frequency hybrid direct sequence spread spectrum receiver structure was proposed.The system adopted maximum ratio combination (MRC) in the frequency domain to achieve equalization and de-spreading processes simultaneously, while achieving optimal reception performance and omitting the IFFT process to reduce computational complexity significantly.On this basis, it was proposed to replace the m-sequence with the constant amplitude zero auto correlation (CAZAC) sequence as the spread spectrum sequence, which significantly improved the system performance without increasing computational complexity.Finally, a high-speed spread spectrum communication method based on cyclic code shift keying (CCSK) was proposed to solve the problems of low spectrum utilization efficiency and limited transmission rate in traditional direct sequence spread spectrum.By utilizing the property of Fourier transform time-domain cyclic shift, a low implementation complexity CCSK decoding method was designed, which reduced the multiplication number required for CCSK de-spreading by O(N²) reduced to O (Nlog N), greatly reducing resource consume.The simulation results show that compared to existing direct sequence spread spectrum methods, the proposed method achieves approximately 3 dB gain in both Gaussian and complex multipath channel environments.…”

Research on incentive mechanism for IoT based on mobile hotspot sharing by Huaizhe LIU, Lin GAO

“…Many devices in the Internet of things,especially energy-constrained sensor devices,often lack efficient network connectivity.If the networking method based on mobile hotspot sharing is adopted,large-area network coverage can be realized efficiently.The basic idea of the networking mode is to activate some mobile node in the cellular network (such as the holders of smart phones and other smart devices) to open mobile hotspot,provide Wi-Fi connections for resource-constrained node,and satisfy the communication needs of these node,so as to achieve efficient access to the mobile Internet.In this networking mode,how to encourage mobile users to contribute hotspot is the key.The incentive mechanism in mobile hotspot sharing network and the impact on network performance was studied mainly,and a novel incentive mechanism was designed to enable some users to obtain certain benefits by contributing Wi-Fi hotspot.Firstly,the optimal sharing decision of different types of users under the incentive mechanism and the influence of decision-making among different users were studied.Then,the evolution of user behavior,the overall state of the network with time and the equilibrium state of the system were analyzed.The simulation results show that under the equilibrium state of the system,the number of mobile hotspot contributors increases with the increase of free traffic ratio,which also leads to an increase in the number of hotspot.If the price of unit traffic is too high,the number of users will be reduced,which is not conducive to the operation of the network.In addition,compared with the non-hotspot sharing network,if the mobile hotspot sharing networking mode is adopted,the network performance can be increased by up to 148%.…”

Reduced phase-state detection based on virtual modulation indexes for Multi-h CPM by Shunqin XIE, Ke ZHOU, Dahai CHEN, Xianglu LI, Sheng ZHONG, Jian ZHANG

“….Simplified detection with reduced phase-state based on virtual modulation indexes was designed for Multi-h CPM.Multiple sets of modulation indexes different from the transmitter were constructed in the receiver,and the per-survivor processing was used to solve the mismatch caused by the inconsistency of the modulation indexes between the receiver and the transmitter.When the denominator of virtual modulation index was much smaller than the original denominator of actual transmitted signal,the phase states of coherent sequence detection could be effectively simplified,thus the complexity of coherent detection for Multi-h CPM could be reduced.The trellis could be simplified further via combining with the frequency pulse truncation(FPT) used for simplifying correlation states.The simulation results show that for advanced range telemetry (ARTM) CPM signal,various simplified receiving schemes based on virtual modulation indexes can be designed.When the virtual modulation indexes are set to <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML"> <mrow><mo>[</mo> <mrow> <mfrac> <mtext>3</mtext> <mtext>4</mtext> </mfrac> <mtext>,</mtext><mfrac> <mtext>2</mtext> <mtext>4</mtext> </mfrac> </mrow> <mo>]</mo></mrow></math></inline-formula>,the number of trellis states can be reduced from 512 (in optimal detection) to 64,but the performance loss is less than 0.05 dB.Further combined with FPT algorithm,the number of trellis states can be reduced to 16,while the performance loss is only 0.75 dB.…”
