Such an ideal assumption may not be met in practical applications where various errors and fluctuations exist in the sensing instruments. This talk considers the problem of compressed sensing subject to a structured perturbation in the sensing matrix. Under mild conditions, it is shown that a sparse signal can be recovered by l1 minimization and the recovery error is at most proportional to the measurement noise level, which is similar to the standard CS result. In the special noise free case, the recovery is exact provided that the signal is sufficiently sparse with respect to the perturbation level. The formulated structured sensing matrix perturbation has practical relevance and is applicable to the direction of arrival estimation problem. Algorithms are proposed to implement the l1 minimization problem and numerical simulations are carried out to verify the obtained results.Biography: Cishen Zhang ( _Ha駇) received the B.Eng. degree in computer engineering from Tsinghua University, China, in 1982 and the Ph.D. degree in electrical engineering from Newcastle University, Australia, in 1990.He was an Electrician with Changxindian (FebruarySeven) Locomotiv  $&(  2 p r x z 熵熵熵烨斓Φ攧u剈剈刢S礎"h.yqh@5丆JOJQJaJo(h.yqh]=5丆JOJQJaJ"h]=h]=5丆JOJQJaJo(h]=5丆JOJQJaJo(h]=h]=5丆JOJQJaJ"h锄h襉5丆JOJQJaJo(hG5丆JOJQJaJo("h锄h@5丆JOJQJaJo( h]=5丆J,OJQJ^JaJ,o(&h锄h梟5丆J,OJQJ^JaJ,o(&h锄h翪5丆J,OJQJ^JaJ,o(4 r & Z -?????????gdkU$d橚[$\$a$gdh_$d橚XD2[$\$a$gd!:Md4gd]= 劋dp`劋gd]=劋勍dpVDWD^劋`勍gd]=dpgd]= $\$a$gd.yqz      镟欣滐袓{i{W郬郬HWh]=5丆JOJQJaJo("h锄ht5丆JOJQJaJo("h锄h籉V5丆JOJQJaJo("h锄h@5丆JOJQJaJo(h@5丆JOJQJaJo("h.yqh.yq5丆JOJQJaJo("h.yqhG5丆JOJQJaJo(h.yqhG5丆JOJQJaJh.yqh(G5丆JOJQJaJh.yq5丆JOJQJaJo(h.yqh.yq5丆JOJQJaJ       $ ( * , 0 < L N R X Z 钴钔芫钔瑲埇芡vfWE"hGh襉5丆JOJQJaJo(h觃5丆JOJQJaJo(h锄h5丆JOJQJaJ"h锄h襉5丆JOJQJaJo("h锄h鏧5丆JOJQJaJo("h锄h籉V5丆JOJQJaJo("h锄h@5丆JOJQJaJo(hG5丆JOJQJaJo(h.yq5丆JOJQJaJo("h锄h5丆JOJQJaJo("h锄hdc$5丆JOJQJaJo(Z d ,-078 橹闹织闹殔o\G1+h.yqh.yq5丅*CJOJQJaJo(ph(h.yqh.yq5丅*CJOJQJaJph%h]=5丅*CJOJQJaJo(ph+h]=h!5丅*CJOJQJaJo(ph(h]=h5丅*CJOJQJaJph(hGh]=B*CJOJQJaJo(ph(h]=h]=B*CJH*OJQJaJph"h]=B*CJOJQJaJo(ph%h]=h]=B*CJOJQJaJph+h]=h 5丅*CJOJQJaJo(ph  ".0VX  J!L!?? ##??0$2$???????????????熳煺熳烀熳熳熳烀烀熳熳熳熳飓槓寪寪寪寑w€mh?EhG5丆J hG5丆J o(h?EhG5丆J o(h3Gjh3GU%hGhGB*CJOJQJaJph.jhGh.yqB*CJOJQJUaJph"h.yqB*CJOJQJaJo(phU(h.yqh.yqB*CJOJQJaJo(ph%h.yqh.yqB*CJOJQJaJph)e Manufactory, Beijing, China, during 1970 1978, carried out research on control systems at Delft University of Technology, the Netherlands, during 1983 1985, was with the Department of Electrical and Electronic Engineering, the University of Melbourne, Australia, as a Lecturer, Senior Lecturer, and Associate Professor and Reader from 1989 to2002, and with the School of Electrical and Electronic Engineering and School of Chemical and Biomedical Engineering, Nanyang Technological University, Singapore, as an Associate Professor during 2002 2010.
