摘要: We address the problem of super-resolution line spectrum estimation an undersampled signal with block prior information. The component frequencies are assumed to take arbitrary continuous values in known frequency blocks. formulate a general semidefinite program recover these continuous-valued using theories positive trigonometric polynomials. proposed achieves recovery by taking advantage structures Numerical experiments show great performance enhancements our method.
