hi david,
take CONSTELLATION FOR THAT I MEAN BPSK OR QPSK
assume taking bpsk
then 1 = BPSK signal of frequnency F ----------------S1
1 = BPSK signal of frequnency 2F ----------------S2
1 = BPSK signal of frequnency 3F ----------------S3
1 = BPSK signal of frequnency 4F ----------------S4
1 = BPSK signal of frequnency 5F ----------------S5
1 = BPSK signal of frequnency 6F ----------------S6

add up all these signals and there is

MAX(COMBINATION OF ALL SIGNALS (S1 TO S6))/AVERAGE OF (S1 TO S6) should
give you the PAPR
