论文摘要
具有动态频谱分配（DSA）的正交频分多访问多访问（OFDMA）能够提供广泛的数据速率要求。本文的重点是在DSA背景下具有低峰值信封功率比（PMEPR）属性的OFDMA系统中的序列序列的设计。我们提出了一个系统的序列序列设计，该序列设计可能会导致较低的PMEPR，以免频谱分配。借助Golay-Davis-Jedwab（GDJ）序列，提出了两类序列序列。我们证明，在四个连续的资源块的一大部分，对于任何DSA，它们的PMEPR在上限为4。
Orthogonal Frequency Division Multiple Access (OFDMA) with Dynamic spectrum allocation (DSA) is able to provide a wide range of data rate requirements. This paper is focused on the design of preamble sequences in OFDMA systems with low peak-to-mean envelope power ratio (PMEPR) property in the context of DSA. We propose a systematic preamble sequence design which gives rise to low PMEPR for possibly non-contiguous spectrum allocations. With the aid of Golay-Davis-Jedwab (GDJ) sequences, two classes of preamble sequences are presented. We prove that their PMEPRs are upper bounded by 4 for any DSA over a chunk of four contiguous resource blocks.
