Abstract :
In this paper we introduce a novel sequence "beta-complementary sequence" to encode the OFDM signals, by which one can substantially increase the code rate while enjoy a tight PMEPR of at most 2. On the other hand, such encoding by beta-complementary sequences has very good trade-off performance between PMEPR and code rate. This observation follows from the properties of beta-complementary sequences investigated by us, the numerical results based on these properties and the comparison with the well discussed Golay complementary sequences and the generalized Golay complementary sequences (called "G N -complementary sequences\´ in this paper).
