A baseband model for computing the peak-to-average power ratio in OFDM systems

The problem of computing the codeword with the highest peak-to-average power ratio in a coded OFDM system is addressed. An approach recently published by Tarokh et al., (2000) is revisited and it is shown that its polynomial complexity in the length of the code can be reduced to linear complexity. The new algorithm is illustrated with some examples.
