With great honor, the City of Xi'an hosts the APSIPA Annual Summit and Conference 2011 (APSIPA ASC 2011). Xi'an, the eternal city, records the great changes of the Chinese nation just like a living history book. Called Chang'an in ancient times, Xi'an is one of the birthplaces of the ancient civilization in the Yellow River Basin area of the country. During 3,100 year development of Xi'an, 13 dynasties such as Western Zhou (11th century BC-771 BC), Qin (221 BC-206 BC), Western Han (206 BC - 24 AD) and Tang (618 - 907) placed their capitals here. So far, Xi'an enjoys equal fame with Athens, Cairo, and Rome as one of the four major ancient civilization capitals in the world. Xi'an enjoys the laudatory title of 'China Natural History Museum'. The Museum of Terra Cotta Warriors and Horses is praised as 'the eighth major miracle of the world', the Mausoleum of Emperor Qin Shi Huang is listed on the World Heritage List, and the Famen Temple holds the precious finger bones of Sakyamuni - the founder of Buddhism¡K
APSIPA ASC 2011 is the third great event of the Asia-Pacific Signal and Information Processing Association (APSIPA). Founded in 2009, APSIPA aims to promote research and education on signal processing, information technology and communications. The annual conference was previously held in Japan in 2009 and in Singapore in 2010. The field of interest of APSIPA concerns all aspects of signals and information including processing, recognition, classification, communications, networking, computing, system design, security, implementation, and technology with applications to scientific, engineering, and social areas. *Accepted papers in regular sessions and accepted papers in special sessions will be published in APSIPA ASC 2011 proceedings which will be indexed by EI Compendex. *

*Submission of Papers*
Prospective authors are invited to submit either full papers, up to 10 pages in length, or short papers up to 4 pages in length, where full papers will be for the single-track oral presentation and short papers will be mostly for poster presentation. The conference is also inviting student researchers to submit 1-page-short-paper to the Student Symposium. Paper submissions to Student Symposium follow the same layout as that of the main conference. The 1-page extended abstract describing the technical contribution should be submitted to the same online paper submission. The conference proceedings of the main conference will be published, available and maintained at the APSIPA website. *The proceedings will be indexed by EI Compendex.*
