METHOD AND APPARATUS OF COMPRESSING A MULTI-CARRIER MODULATION SIGNAL IN FREQUENCY DOMAIN

摘要

The invention provides a method and an apparatus, of compressing a multi-carrier modulation signal in frequency domain. By setting a modulation mode indicator, the preferable technical scheme could be changed dynamically according to the modulation mode, so as to select the corresponding bits for the different modulation mode. Moreover, according the preferable technical scheme of the present invention, the signal of the data channel in the resource element after extracting the second scale factor is represented by the bits which are occupied by a pair of I/Q signal. Thus, more bits are saved and compression ratio is enhanced.
