Reduction of out-of-band radiation in OFDM systems by insertion of cancellation carriers
TL;DR: This letter investigates a new method for sidelobe suppression characterized by the insertion of a few so-called cancellation carriers at both sides of the OFDM spectrum that achieves a significant reduction of out-of-band radiation.
Journal ArticleDOI
Subcarrier weighting: a method for sidelobe suppression in OFDM systems
TL;DR: The proposed method is based on the multiplication of the used subcarriers with subcarrier weights, which reduces OFDM sidelobes by more than 10 dB in the average without requiring the transmission of any side information.
Book ChapterDOI
Interleaved FDMA-a new spread-spectrum multiple-access scheme
TL;DR: A new spread-spectrum multiple- access scheme applicable for both the uplink and the downlink of a mobile radio communications system is proposed, which is termed "interleaved frequency-division multiple-access", which combines the advantages of spread-Spectrum and multicarrier transmission.
Proceedings ArticleDOI
Sidelobe suppression in OFDM systems by insertion of cancellation carriers
TL;DR: Simulation results show that with the proposed method a significant sidelobe suppression is achieved with only a small loss in bit error rate performance.
Journal ArticleDOI
LDACS: future aeronautical communications for air-traffic management
TL;DR: The most promisingLDACS technology candidate, LDACS1, is described in detail, and possible extensions toward navigation and surveillance are discussed, with special focus on the air/ground communications technology L-band Digital Aeronautical Communications System.
