In this Letter, a new construction of complementary sequence sets (CSSs) is proposed by concatenating Golay complementary pairs (GCPs) which could have different lengths. The constructed CSSs have flexible sequence lengths, i.e. , where L and N are the lengths of two constituting GCPs. For example, the proposed method can be used to construct quadriphase CSSs of all lengths up to 100, except 87 and 95. The feasibility for practical applications of CSSs will be enhanced due to their flexible lengths and good peak-to-average power ratio property.

基于互补对的互补序列集的构建

在这封信中，通过连接可能具有不同长度的 Golay 互补对 (GCP)，提出了一种新的互补序列集 (CSS) 构造。构建的 CSS 具有灵活的序列长度，即其中 L 和 N 是两个组成 GCP 的长度。例如，所提出的方法可用于构建除 87 和 95 之外的所有长度的四相 CSS。由于其灵活的长度和良好的峰均功率比特性，CSS 在实际应用中的可行性将得到增强.
