Reduction of out-of-band emitted power

摘要

OFDM signal transmission of reduced power emission outside a designated transmission bandwidth is disclosed. At least one subcarrier is allocated for an OFDM symbol for non-data. A weighting signal representation is determined based on an initial error signal representation, which is determined from at least part of a first OFDM symbol and part of a second OFDM symbol, the first and second OFDM symbols being consecutive in time.
