Signal Design for Interference Reduction Heading link
A focus area of our research in WaveOPT LAB is the design of sequences with excellent interference reduction properties— particularly those with small auto/cross-correlation. Such sequences form an essential component of a large set of information processing systems, ranging from information collection in active sensing, to information embedding and transmission in communication systems. For instance, they are widely used in Code-Division Multiple-Access (CDMA) schemes to distinguish between different users while at the same time enabling the system to synchronize, whereas in active sensing applications, usage of such sequences for pulse modulation paves the way to conveniently retrieve the received signal from the range bin of interest by employing a matched filter, and thus suppress inputs from other range bins.
