Exploiting the statistical properties of strictly non-circular (NC) signals in direction of arrival (DOA) estimation has long been an active area of research due to its associated performance improvements. Recently, this concept has been introduced to DOA estimation via sparse signal recovery (SSR), where similar benefits from processing NC signals are achieved. However, the standard approach to NC...
In this paper, we introduce a nonuniform sparsity model and analyze the performance of an optimized weighted ℓ1 minimization over that sparsity model. In particular, we focus on a model where the entries of the unknown vector fall into two sets, with entries of each set having a specific probability of being nonzero. We propose a weighted ℓ1 minimization recovery algorithm and analyze its performance...
