Abstract :
In this paper, we present a new selective mapping (SLM) approach that integrates peak-to-average power ratio (PAPR) reduction with error control (EC) in OFDM systems. We call this new scheme EC-SLM coding. EC-SLM coding has a simple coding structure and does not require transmission of side information. Several well-known linear EC codes such as convolutional codes, turbo codes, and LDPC codes can be included in EC-SLM coding. Performance of EC-SLM coding is evaluated.
