Abstract

Selective mapping (SLM) has been employed to reduce the peak interference-to-carrier ratio (PICR) in OFDM systems. Here, we significantly reduce the computational complexity of SLM using subsets of intermediate signals within the inverse fast Fourier and fast Fourier transforms, while achieving performance close to that previously obtained.
