DESIGN OF UNIMODULAR SEQUENCE SETS WITH GOOD CORRELATION AND COMPLEMENTARY CORRELATION PROPERTIES

Abstract

The design of sequences with good correlation properties has been of long-standing interest in signal processing owing to their applications in diverse fields of technology. The computational construction of such sequences typically relies on the minimization of Integrated Sidelobe Level (ISL)-related metrics that effectively lower the correlation magnitude for out-of-phase lags. In this paper, we address the design of sets of unimodular sequences with good cross-correlation and complementary cross-correlation properties over a zero-correlation-zone. Numerical results show the potential of the generated sequences in identifying both strictly linear (SL) and widely linear (WL) systems.
