TRANSMITTER APPARATUS FOR CONDITIONING A MULTICARRIER SIGNAL, NETWORK NODE, METHOD FOR CONDITIONING A MULTICARRIER SIGNAL, AND COMPUTER PROGRAM THEREOF

摘要

The embodiments of the invention relate to a transmitter apparatus (TA1) for conditioning a multicarrier signal (RFS). The transmitter apparatus (TA1) contains means (FE-PU) for grouping subcarriers of the multicarrier signal (RFS) into a first frequency block, which contains a first group of the subcarriers and into at least a second frequency block, which contains at least a second group of said subcarriers. The transmitter apparatus (TA1) further contains first filtering means (LPF-1) for sideband suppression outside of the first frequency block and at least second filtering means (LPF-2, LPF-M) for simultaneous and separate sideband suppression outside of the at least second frequency block. The embodiments of the invention further relate to a method for conditioning a multicarrier signal (RFS). The method contains grouping subcarriers of the multicarrier signal (RFS) into a first frequency block, which contains a first group of said subcarriers and into at least a second frequency block, which contains at least a second group of said subcarriers. The method further contains filtering the first frequency block for sideband suppression outside the first frequency block, and filtering the at least second frequency block for simultaneous and separate sideband suppression outside the at least second frequency block. The embodiments of the invention even further relate to a computer program having a program code for performing the method, when the computer program is executed on a computer or processor and to a network node, which contains the transmitter apparatus.

1. A transmitter apparatus for conditioning a multicarrier signal, said transmitter apparatus comprising:
means for grouping subcarriers of said multicarrier signal into a first frequency block comprising a first group of said subcarriers and into at least a second frequency block comprising at least a second group of said subcarriers, means for performing a Fourier transformation of said first frequency block and of said at least second frequency block for generating a first part and at least a second part of a time domain signal, first filtering means for filtering said first part and for sideband suppression outside of said first frequency block, and at least second filtering means for filtering said at least second part and for simultaneous and separate sideband suppression outside of said at least second frequency block.
