Abstract
A wireless transmitter is configured to map N first samples of a first discrete Fourier transform (DFT) of a group of coded symbols to M sub-carriers according to a first sub-carrier mapping rule. In this case, M is greater than N. The wireless transmitter is also configure to perform a first inverse DFT (IDFT) on the M sub-carriers to provide M second samples and clip the M second samples according to a clipping rule to provide M third samples. The wireless transmitter is further configured to perform a second DFT on the M third samples, de-map the M third samples to N fourth samples, and map the N fourth samples to O subcarriers according to a predetermined second subcarrier mapping rule. In this case, O is greater than or equal to M.
