    Abstract: OFDM generation apparatus and methods generating OFDM transmission signals from OFDM symbols, each including a plural OFDM subcarriers, for transmission in a multi-carrier data transmission system. In OFDM systems using the concept of Absolute OFDM and/or using Segmented OFDM common phase rotations of the OFDM subcarriers of the OFDM symbol with respect to adjacent OFDM symbols of the OFDM transmission signal generally appear. To avoid or compensate those common phase rotations, in the apparatus and method a selected mixing frequency is used for mixing the complex time-domain samples of the OFDM symbol from a baseband frequency up to a passband frequency by use of a mixing frequency to obtain the OFDM transmission signal, wherein the mixing frequency is selected such that common phase rotations of the OFDM subcarriers of the OFDM symbol with respect to adjacent OFDM symbols of the OFDM transmission signal are avoided or compensated after the mixing.
