Method for spectral side lobe suppression in OFDM-based communication system |
摘要 |
The invention relates to N subcarriers of an OFDM communication system or OFDM based multi-carrier communication system M subcarriers used as cancellation subcarriers to achieve side lobe suppression of the OFDM transmission signal, where M<N. The M cancellation subcarriers are scaled with a generally complex weighting factor. Determining the weighting factor is performed in accordance with a suitable optimization criterion. Application in OFDM-based wireless and wired communication systems.
