Using a realization of 16-QAM as set addition of two scaled versions of the
4-PSK constellation, we construct 16-QAM sequences having low peak-to-mean
envelope power ratios (PMEPR) from I-PSK Golay sequences. Various upper bo
unds on the peak envelope powers of these sequences are established. Transm
ission using these sequences provides twice as much rate as transmission us
ing complementary Golay sequences with a maximum PMEPR of 3.6 (5.56 dB).
