In this paper, we propose four low complexity
partial transmitted sequences (PTS) algorithms that are based on
the tree diagram for peak-to-average power ratio (PAPR) reduction
in orthogonal frequency division multiplexing (OFDM) systems. The
prorpsed algorithms can obtain all phase factors by searching the
tree diagram of different $(n,k)$ linear block codes, and then
select an OFDM signal with minimum PAPR for transmitting and
transmit the side information with error correction. Compare
conventional PTS (C-PTS) with our algorithms, you will know our algorithms which are low computational complexity for searching phase factors. Therefore, there are two main advantages in our algorithms , i.e. lower searching complexity and the side information provides extra error-correction property.
