However, they may cause severe inter-cell cross-link interference (CLI). In allusion to the problem mentioned above, this paper presents a modified power control (MPC) algorithm which has low complexity and high flexibility for above issue. The purpose of MPC is to coordinate the CLI by dynamically adjusting the step size of power control so that the transmit power can quickly converge to the target value. And the adjustment process is first quick back slow so that transmit power decreasing rapidly in early stage can make the coordination effect on CLI more obvious. Besides, the algorithm also sets a margin to eliminate the problems that the adjustment process is endless and the power oscillates around the target. Through the simulations, it is verified that MPC can improve effectively system performances which improve SINR around 3dB and doubles the speed of adjustment process compared with other algorithms involved in simulations.","PeriodicalId":382686,"journal":{"name":"2019 IEEE 2nd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126917185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with conical scanning radars, monopulse radars boast high angular accuracy, fast speed and strong capacity for resisting angle deception jamming. Cross-polarization jamming can make use of the complex structure of the monopulse antenna pattern to generate angle deception jamming. This paper has firstly given the principle for angle measurement of phase comparison monopulse radars, designed the model of the cross-polarization pattern, established the model for angle measurement of the cross-polarization jamming and presented the reduction status of the angle measurement performance in the jamming environment by means of mathematical simulation. It can be seen that antenna pattern has different polarization structure. When the jamming intensity is enough, the cross-polarization jamming will reduce the accuracy of radar angle measurement by 40% which will degrade the tracking performance of radar.","PeriodicalId":382686,"journal":{"name":"2019 IEEE 2nd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131497042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mismatch might be caused by the array imperfections such as mutual coupling, gain and phase uncertainties, sensor position perturbation. In this paper, a new blind beamforming algorithm under intensive interferences for arrays having arbitrary uncertainties is proposed. By utilizing the fact that in the presence of intensive interferences the steering vector of the signal of interest (SOI) can be well approximated by an eigenvector of the array covariance matrix, one can obtain an estimate interference-plus-noise covariance (INC) matrix. Thus, a blind beamformer can be achieved by substituting the reconstructed INC and steering vector of SOI back into the SCB. Unlike most of the existing approaches, the proposed method does not need to know the direction of the SOI or the information of the uncertainties. Simulation results indicate that the proposed method is able to provide superior performance compared with existing approaches.","PeriodicalId":382686,"journal":{"name":"2019 IEEE 2nd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116691410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
