A Golay code based approach to reduction of the PAPR and its consequence for the data throughput

OFDM is considered as the basis of a radar system that combines radar and communication for fusion of target information from several radars. High PAPR of OFDM causes signal distortion during amplification. PAPR control by coding trades communication throughput for radar performance. The novelty of the paper is in the approach to this trade-off. Several relations between phase sequences with the same PAPR value are investigated. Bit rate reduction due to PAPR limiting by Golay complementary sequences is considered. It is shown that with increasing number of carriers the fraction of Golay sequences of all sequences satisfying a PAPR limit declines rapidly.
