A block coding scheme has previously been proposed using maximal-lengt
h sequences to reduce the peak-to-average power ratio (PAP) for orthog
onal frequency division multiplexing (OFDM). It has also been claimed
that PAP can be limited to the range 0.08 - 0.6dB for some m-sequences
. These numbers are incorrect and m-sequences can only yield PAP value
s in the range 5 - 7dB.
