Orthogonal frequency division multiplexing (OFDM) system has the problem of high peak-to-average power ratio (PAPR) due to its multiple sub-carriers. In general, partial transmitted sequence (PTS) technique is applied to obtain optimal PAPR reduction performance, but its exhausted search for the optimal phase factors must be accomplished accordingly. As the number of sub-blocks and phase factors increase,...
Partial transmit sequence (PTS) is an effective technique to reduce the peak-to-average power ratio (PAPR) for orthogonal frequency division multiplexing (OFDM) transmitter. However, selecting the optimal parameters for the PTS is very complex since it requires an exhaustive search of all possible weighting factors whose number grows exponentially with the number of subblocks. An improved particle...
