In recent years one of key technologies of 5G, the filter bank multicarrier with offset quadrature amplitude modulation (FBMC-OQAM) has been studied widely by many researchers. In this paper, the problem of peak-to-average power ratio (PAPR) reduction is considered for FBMC-OQAM systems using cuckoo search optimization algorithm(CSOA). Because of overlapping structure of FBMC-OQAM signals the CSOA...
Filter bank multi-carrier with offset QAM(FBMC/OQAM) is a multi-carrier modulation technique that can be an alternative to conventional orthogonal frequency division multiplexing(OFDM) with cyclic prefix (CP) in wireless network. FBMC has a higher spectrum efficiency and effective emission power without CP. Because the orthogonality only exists in real domain, the channel estimation in FBMC/OQAM system...
Step Frequency Radar and interferometric technique can be combined to measure the displacement of a bridge. Based on the reason of ambiguous high resolution range profiles of stepped frequency radar, the algorithms to achieve unambiguous high resolution range profiles is analyzed. And a new algorithms to achieve real one-dimensional profiles is proposed. Secondly, because of the ambiguous displacement...
Microeconomics has become a basic core curriculum for students in economics, finance and management major. But in practice, there are many difficulties in teaching and studying. Microeconomics is often considered to be too complex and too theoretical. We try to use the audio-visual approach to improve the microeconomics teaching effect. The results show that this method is helpful both for deepening...
U-I collaborative Innovation has become an imperative for both universities and companies to strengthen their values and to remain competitiveness gained. This paper, Firstly based on U-A model and dominant design perspective, identifies three key controllable factors which affecting U-I innovation performance as research hypothesis; Secondly, based on the acquisition of 551 questionnaires and the...
Adaptive front lighting system(AFS) is most advanced vehicle lighting system, which can greatly reduce driverpsilas fatigue degree when driving on curve road at night, make driver clearly see actual road surface at turn around, make driver have abundant time to deal with emergency, and evidently promote safety at night. Most high class vehicles have been fixed AFS in Japan, meanwhile AFS will be used...
Spiritual quotient is emerging as a new concept of spiritual ability. It is obvious different with material ability. As a kind of brainwork, research needs more personal spiritual ability not material ability than physical work. This paper focuses on Ph. D candidates who play important role in university research work but without drawing much academic attention. In this research, we first construct...
The primary goal for wireless sensor MAC protocol is energy conservation. S(sensor)-MAC based on sensor networks proposes schemes such as periodic sleep and overhearing avoidance for that goal. An analytic model of CAP is employed for our probability model of active period for minimizing energy consumption in a S(sensor)-MAC. We evaluate the time for one successful transmission so that nodes can go...
