Indirect spectrum sensing mainly concerns the measurement and analysis of primary wideband analog signal. This paper proposes two robust algorithms based on maximum a-posteriori probability (MAP) and minimum mean-squared error (MMSE) estimators to recover wideband block-sparse spectrum and then dete...
