论文摘要
在许多5G无线系统中，都需要具有低相关性旁路级（SLCL）的OFDM序列。在这封信中，OFDM序列和不匹配滤波器的共同设计是为了在光谱和峰值与平均功率比（PAPR）的限制下实现SLCL。具体而言，我们通过最大化OFDM序列和不匹配滤波器之间的互相关的峰侧叶比（PSLR）来提出优化问题，但要受到多种练习约束。为了解决非凸问题，提出了有效的交替优化（ALTOPT）算法。提供了数值模拟以证明所提出算法的有效性。
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.
