A circuit and method provides subcarrier puncturing by placing no
information in subcarriers that suffer from channel impairments where
they cannot deliver information. If no energy is placed in these
subcarriers, then the transmitted power may be re-allocated to the
information carrying subcarriers to increase the Signal-to-Noise Ratio
(SNR) at the target node. Or, energy may be place in subcarriers that
suffer from channel impairments, but the PAPR of the OFDM symbol may be
reduced.
