A Simple Construction of 16QAM Codewords with Low PMEPR for OFDM Signals
"... Abstract—Golay sequences have been introduced to construct 16QAM (quaternary amplitude modulation) code for the orthogonal frequency division multiplexing (OFDM), reducing the peaktomean envelope power ratio (PMEPR). As an alternative way to construct Golay sequences, the construction of 16QAM ..."

Nearcomplementary Sequences With Low PMEPR for Peak Power Control in Multicarrier Communications
, 2009
"... New families of nearcomplementary sequences are presented for peak power control in multicarrier communications. A framework for nearcomplementary sequences is given by the explicit Boolean expression and the equivalent array structure. The framework transforms the seed pairs to nearcomplementary ..."

complementary sequences by the aid of Golay complementary sequences. As the first example, a new sequence family of length 2m and peaktomean envelope power ratio (PMEPR) ≤ 4 is presented, where the family produces more distinct sequences than any other known near complementary sequences of the same lengths and PMEPR

mathematical framework for generating solutions to this notorious problem that are suited to lowcost wireless applications. The key result is a connection between Golay complementary sequences and ReedMuller codes. The former are almost ideal for OFDM transmissions because they have a very low peak
Signal Design and Coding for HighBandwidth OFDM in CartoCar Communications
"... Abstract—We analyse mobile propagation channels which occur in the context of cartocar communications in the 24 GHz ISM band. From the information gathered, we design robust frame designs for combined radar and communication systems using highbandwidth OFDM signals. Two solutions are proposed: t ..."

Construction of block orthogonal Golay sequences and application to channel estimation of MIMOOFDM systems
 IEEE Trans. Commun
, 2007
"... Abstract — In this paper, we construct a family of block orthogonal Golay sequences that have low peaktomean envelope power ratio (PMEPR) as well as blockwise orthogonal properties. We then present an application of the sequences to channel estimation of multipleinput multipleoutput orthogonal f ..."

another. Since Golay sequences give low PMEPR, it is natural to use them for OFDM systems. This is particularly true for the pilot sequences of the MIMOOFDM system. It must be noted that low PMEPR of the pilot sequences allows power boosting of pilot signals compared with data signals, improving
complementary Sequences and PeaktoMean Envelope Power Ratio Reduction in OFDM
