Sets of sequences with good correlation properties are desired in many active sensing and communication systems, e.g., multiple-input-multiple-output (MIMO) radar systems and code-division multiple-access (CDMA) cellular systems. In this paper, we consider the problems of designing complementary sets of sequences (CSS) and also sequence sets with both good(More)
Sequences with low aperiodic autocorrelation sidelobes are well known to have extensive applications in active sensing and communication systems. In this paper, we first consider the problem of minimizing the weighted integrated sidelobe level (WISL), which can be used to design sequences with impulse-like autocorrelation and a zero (or low) correlation(More)
Unimodular sequences with low autocorrelation are desired in many applications, especially in radar systems and code-division multiple access (CDMA) communication systems. In this paper, we propose a new algorithm to design unimodular sequences with low autocorrelation via directly minimizing the integrated sidelobe level (ISL) of the autocorrelation. The(More)
In this paper, we consider an &#x2113;<sub>0</sub>-norm penalized formulation of the generalized eigenvalue problem (GEP), aimed at extracting the leading sparse generalized eigenvector of a matrix pair. The formulation involves maximization of a discontinuous nonconcave objective function over a nonconvex constraint set, and is therefore computationally(More)
—Semidefinite relaxation (SDR) provides a computa-tionally efficient polynomial-time approximation of the maximum likelihood detector. However, most of the existing works mainly focus on particular signal constellations. In this paper, we propose a universal binary semidefinite relaxation scheme that can handle arbitrary signal constellations in polynomial(More)
In this paper, we consider the low autocorrelation sequence design problem. We optimize a unified metric over a general constraint set. The unified metric includes the integrated sidelobe level (ISL) and the peak sidelobe level (PSL) as special cases, and the general constraint set contains the unimodular constraint, Peak-to-Average Ratio (PAR) constraint,(More)
Sequences with low aperiodic autocorrelation sidelobes are well-known to have extensive applications in active sensing and communication systems. In this paper, we consider the sequence design problem of minimizing the &#x2113;p-norm of the autocorrelation side-lobes, which can then be used to minimize the peak sidelobe level (PSL) criterion. An algorithm(More)
Unimodular sequences with low autocorrelations are desired in many applications, especially in the area of radar and code-division multiple access (CDMA). In this paper, we propose a new algorithm to design unimodular sequences with low integrated sidelobe level (ISL), which is a widely used measure of the goodness of a sequence's correlation property.
