Large dynamic range microwave photonics mixing system based on parallel DPMZM by Yongsheng GAO, Fangjing SHI, Jiajun TAN, Yangyu FAN

“…To solve the problems of nonlinear distortion and limited dynamic range of microwave photonics mixing system, a large dynamic range microwave photonics mixing system based on parallel dual parallel Mach-Zehnder modulator (DPMZM) was proposed.The parallel modulation of radio frequency and local oscillator signals was realized by using DPMZM.The third-order intermodulation distortion (IMD3) in the output intermediate frequency signal was eliminated by configuring the electro-optic modulation index of the two parallel channels and the working point of the modulators.Finally, the dynamic range of the system was improved.Simulation results show that the proposed scheme can suppress IMD3 by 17.7 dB and increase the SFDR to <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML"> <mn>127.8</mn><mtext> dB</mtext><mo>·</mo><msup> <mtext>Hz</mtext> <mrow> <mfrac> <mn>4</mn> <mn>5</mn> </mfrac> </mrow> </msup> </math></inline-formula> .…”

Dynamic switching based real-time routing in low-duty-cycle wireless sensor networks by Quan CHEN, Hong GAO

“…The dynamic switching based real-time(DSRT)routing protocol was proposed to handle the arbitrary end-to-end(E2E)real-time communication in the low-duty-cycle wireless sensor networks.Firstly,the concept of available speed was designed to compensate for the big sleep latency and facilitate discovering the routes with less latency based on two-hop neighbors’ information(at lease about 20% routing path with less latency was discovered by DRST in the experiments).Moreover,it was noticed that the congestion extent in the low-duty-cycle network was determined not only by the number of packets in the network output queue,but also the destination of the packets.However,the traditional method with one-hop neighbors’ information cannot differentiate this kind of congestion.Therefore,combined with the dynamic switching mechanism,the DSRT proposed a congestion avoiding algorithm by classifying the packets in the queue.Through comprehensive experiments,the efficiency of routing discovering and congestion avoiding of the DSRT protocol is demonstrated,and the E2E delay is decreased by at least 200% when the traffic was high.…”

Overview of research progress on blind separation methods for single channel communication signal by Wen DENG, Zhitao HUANG, Xiang WANG

“…Significant progress has been made in the research of single channel blind signal separation (SCBSS) methods, as the theoretical and practical applications of SCBSS technology have been continuously improved.A new classification framework for blind signal separation (BSS) of communication signal problems was proposed based on an analysis of a large number of academic research results from both domestic and international sources.The division of SCBSS problems into four levels: multi-signal waveform separation, single-signal waveform separation, multi-signal symbol sequence separation, and single-signal symbol sequence separation was determined by taking into consideration the demand for output results of BSS systems in different application scenarios.Subsequently, the research status of SCBSS methods was systematically reviewed.Furthermore, the current research status of data-driven SCBSS was summarized, and the problems and solutions that needed to be addressed in data-driven SCBSS technology were explored.Finally, several potential research directions for SCBSS were analyzed and forecasted.The aim is to provide a reference for the research and application of SCBSS.…”
