Abstract :
Partial transmit sequence (PTS) is a widely accepted method in reducing PAPR of OFDM signal. While traditional optimal PTS (OPTS) technique requires an exhaustive search over and computation is huge. In this paper, a fusion algorithm based on modified interleaved partition PTS and nonlinear companding transformation is presented. The algorithm set a threshold in IPTS and combine the companding transformation to reduce the computational complexity. It can achieve the same PAPR performance but at lower computational complexity compared with IPTS and companding transformation.
