Transmission and reception of a wideband signal with narrowband interference

An apparatus, comprising:

• means for retrieving a first carrier signal from a received transmission signal comprising a plurality of subcarrier signals of the first carrier signal each of which subcarrier signals being interfered by an effective interference of a modulated second carrier signal, wherein the means for retrieving further comprises means for subtracting a generated replica of the second carrier signal from the received transmission signal;
• means for generating, prior to the subtracting performed by the means for subtracting, the replica of the second carrier signal, the means for generating comprising:
• means for demodulating the decoded transmission signal;
• means for decoding the received transmission signal;
• and
• means for filtering the demodulated and decoded transmission signal for removing the subcarrier signals overlapping the modulated second carrier signal in bandwidth.

An apparatus comprising:

• at least one processor;
• and
• at least one memory including computer program code, where the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to at least:
• retrieve a first carrier signal from a received transmission signal comprising a plurality of subcarrier signals of the first carrier signal, each of which subcarrier signals being interfered by an effective interference of a modulated second carrier signal wherein the retrieving is performed by subtracting a generated replica of the second carrier signal from the received transmission signal;
• prior to the subtracting, generate the replica of the second carrier signal by:
• demodulating the decoded transmission signal;
• decoding the received transmission signal;
• and
• filtering the demodulated and decoded transmission signal for removing the subcarrier signals overlapping the modulated second carrier signal in bandwidth.
