Sequence sets with good correlation properties lie at the core of many communication and radar applications. A new approach to the design of sequence sets is proposed. The ideal correlation matrix is defined, and the design problem is formulated as a power spectral density (PSD) fitting problem. In this manner, a simpler minimisation problem is obtained, and an iterative method is applied to solve it. Simulation results demonstrate that the performance of the proposed approach is superior to that of the previous state‐of‐the‐art algorithm.
