Abstract: In cognitive radio (CR) networks with non-continuous carriers, designing spectrally-null-constrained (SNC) sequences with good correlation properties is an important research task. In this letter, two types of SNC sequences with zero correlation zone (ZCZ) property… read more here.

DOI: 10.1109/lsp.2023.3280852
Abstract: Both the null-constrained method and the Jacobi-Anger expansion method are commonly adopted to design the fully steerable circular differential microphone arrays (CDMAs). So far, these two methods have been independently studied, and it is unclear… read more here.
