具有低PMEPR的OFDM的新代码

New Codes for OFDM with Low PMEPR

Kai-Uwe Schmidt, Adolf Finger

摘要:

本文提出了一种新的峰均包络功率比(PMEPR)严格控制的正交频分复用(OFDM)码。我们确定了一个新的家庭的序列发生在互补集,并表明,这样的序列形成子集的一个新的推广的里德-穆勒码。与以前的建设,我们提出了一个紧凑的描述,这样的代码,这使得他们适合更大的块长度。我们还证明了一些先前的构式只是作为特例出现在我们的构式中。

英文摘要:

In this paper new codes for orthogonal frequency-division multiplexing (OFDM) with tightly controlled peak-to-mean envelope power ratio (PMEPR) are proposed. We identify a new family of sequences occuring in complementary sets and show that such sequences form subsets of a new generalization of the Reed--Muller codes. Contrarily to previous constructions we present a compact description of such codes, which makes them suitable even for larger block lengths. We also show that some previous constructions just occur as special cases in our construction.
