The OFDM sequences with low correlation sidelobe level (SLCL) is desired in many 5G wireless systems. In this letter, the OFDM sequences and mismatch filter are jointly designed to achieve the SLCL under the constraints of spectra and peak to average power ratio (PAPR). Specifically, we formulate the optimization problem by maximizing the peak side lobe ratio (PSLR) of the cross-correlation between the OFDM sequences and mismatch filter, subject to several practice constraints. To solve the nonconvex problem, an efficient alternating optimization (AltOpt) algorithm is proposed. Numerical simulations are provided to demonstrate the effectiveness of the proposed algorithms.
