Payload generation in ofdm benchmark scripts

Hello,

I am trying to figure out how the payload is generated in ofdm benchmark
scripts. I figured how the preambles are generated and used using the
known_symbols arrays in ofdm.py. I am also being able to print the
payload
that is transmitted on the screen. The payload starts with 10,11,12 and
so
on till FF(for bpsk modulation). But which file actually generates this
sequence? I was looking at the gr_ofdm_mapper_bcv.cc but couldn’t figure
out
the logic. Can anyone please help me out?
