A band-limited receiver technology based on PAM4 modulation for the short distance optical transmission system by Qun LIU, Huiqin DU, Xianglin WU

“…In intensity modulation and direct detection of the short distance optical transmission system,there is some serious ISI (inter symbol interference) for the detected PAM4 signal due to the band-limited performance for the optical devices.A band-limited compensation algorithm based on DFE (decision feedback equalizer) combined FTN (fast than Nyquist) transmission was proposed.Then the algorithm performance gain was simulated in different band-limited scenarios,and the simulation results show that this algorithm can be useful to demodulate PAM4 receiver signal.What is more,there is about 1 dB performance gain at the bit error rate (BER) of 10^-3for the serious conditions.…”

An exceptional cluster algebra for Higgs plus jet production by Rigers Aliaj, Georgios Papathanasiou

“…Abstract A recent evaluation of three-loop nonplanar Feynman integrals contributing to Higgs plus jet production has established their dependence on two novel symbol letters. We show that the resulting alphabet is described by a G 2 cluster algebra, enlarging the C 2 cluster algebra found to cover all previously known integrals relevant for this process. …”

Development status and trend of space information network and laser communication by Huilin JIANG, Qiang FU, Yiwu ZHAO, Xianzhu LIU

“…An integrated space-earth information network is an important symbol of a strong country in science and technology.According to China’s overall plan,an information network with global coverage,on-demand services,local access and security and credibility will be built by 2030 to serve national defense and social development.Space laser communication is an important means to realize high speed information transmission and security.Firstly,space-earth integration network was introduced from three aspects:concept connotation and system architecture,research status and development trend,overall goal and main difficulties.Then,the concept,characteristics,research status and development trend of space laser communication were summarized in order to provide useful reference for the construction of space-earth integrated information network in China.…”

Novel method of spread spectrum communication by Jia-fang KANG, Hong-xing WANG, Zhi-yong ZHAO, Zhong-yang MAO, Xi-guo LIU, Chuan-hui1 LIU

“…As the bandwidth efficiency of traditional spread spectrum modulation is quite low,a novel spread spectrum communication method,which uses the relative position of the spread spectrum modulation symbol to carry information was presented,and the method establishes the relationship between the information transfer rate and the spreading code or the transmission bandwidth.Theoretical analysis and simulation results show that the modulation method can not only greatly improve the bandwidth efficiency of the spread spectrum system,but also effectively combat broadband,narrow-band or other spread spectrum interference.This method provides some novel ideas for the future research of spread spectrum communications.…”

Poétiques mémorielles et imaginaire collectif : canne à sucre et émancipation en Caraïbe by Sandra Monet-Descombey Hernández

“…The sugar plantation (economy, society, identity) tends to disappear from current landscapes but still represents a symbol of historical resistance as well as the common expression of interregional Caribbean identity; besides, it remains a reconceptualized theme in the theoretical essays of many Caribbean authors from the beginning of the 21st century until today.…”

Performance analysis of amplify-and-forward cooperative communication systems with imperfect channel estimation by WANG Lei, CAI Yue-ming, YANG Wei-wei, TU Jia

“…The impact of channel estimation errors on the performance for two-hop multi-relays assisted am-plify-and-forward（AF） cooperative communication systems was investigated.Closed-form expressions of the average symbol error rate,as well as the diversity gain under different channel estimation quality orders for both opportunistic re-laying（OPR） and all-participate relaying（APR） schemes were derived.Average signal-to-noise-ratio（SNR） gap ratio is investigated for the two types of cooperative communication systems,which lead to a conclusion that the OPR scheme is more susceptible to channel estimation errors than the APR scheme.Numerical results verify the theoretical analysis.…”
