Patent ID: 7693118

Claim:
A method for spectral side lobe suppression of the transmitter signal in wireless or wired orthogonal frequency-division multiplexing (OFDM) communication systems and in OFDM or OFDM-based multicarrier communication systems, wherein each subcarrier in the OFDM or OFDM-based multi-carrier communication system is multiplied with real or complex weighting factors, each weighted subcarrier being determined according to s _ n ⁡ ( x ) = g n · s n ⁡ ( x ) = g n · d n · sin ⁡ ( x - x n ) x - x n , n = 1 , … ⁢ , N . each weighting factor g n being determined for each OFDM symbol sequence separately so that in accordance with an optimization criterion the spectral side lobes of each OFDM symbol sequence of an OFDM transmission of the communication system are minimized.
