Following the success of the first IEEE workshop on Computational Advances in Multi-Channel Sensor Array Processing, held in Dec. 2005 at Puerto Vallarta, Mexico, we are pleased to announce the second workshop in this series, sponsored by the Sensor Array and Multi-channel signal processing Technical Committee of the IEEE Signal Processing Society. CAMSAP 2007 will be held at the Wyndham Sugar Bay Resort in the U.S. Virgin Islands, and will feature a number of plenary talks from the world’s leading researchers in the area, special focus sessions, and contributed papers. As in CAMSAP2005, both contributed and invited special session papers will undergo peer review, in order to provide feedback to the authors and ensure a high-quality program.
