CCE-OMBOC: A Simple and Efficient Constant-Envelope Technology for Multicarrier Navigation Modulation by Clipping

Remote Sensing
Multicarrier navigation modulation is a trend within next-generation global navigation satellite systems (GNSS) aiming to enhance navigation performance, but it forces amplifiers to work in nonsaturation zones, resulting in low power efficiency.

An industrial Internet-of-things URLLC system via cross-layer design for anti-jamming

Dianxin kexue
The classical OFDM multicarrier waveforms for transmission are adopted by the existing 5G/B5G URLLC standard (3GPP R17-18), and less attention is paid to the anti-interference strategy of URLLC-OFDM multicarrier transmission due to its operation in the ...

CDMA Transmission with Complex OFDM/OQAM

EURASIP Journal on Wireless Communications and Networking, 2008
We propose an alternative to the well-known multicarrier code-division multiple access (MC-CDMA) technique for downlink transmission by replacing the conventional cyclic-prefix orthogonal frequency division multiplexing (OFDM) modulation by an advanced ...

Bit Error and Packet Error Probability for Rectangular Mary-QAM in OFDM Transmission System over Rayleigh Fading Channels

Journal of Engineering and Sustainable Development, 2007
Orthogonal frequency division multiplexing (OFDM) or multicarrier transmission has been shown to be an effective technique to combat multipath fading in wireless communications. It has been successfully used for HF radio applications and has been chosen
