Abstract
A wireless transmission device capable of communicating with a receiver according to a DFT-spread OFDM protocol. The wireless transmission device comprises a configurable spectral shaping filter block capable of performing spectral shaping of an outgoing signal. The wireless transmission device configures the configurable spectral shaping filter block to perform spectral shaping according to a peak-to-average power (PAPR) value associated with the outgoing signal. The multi-carrier protocol comprises one of orthogonal frequency division multiple access (OFDMA) and orthogonal frequency division multiplexing (OFDM).
