On multicarrier modulation for train-to-wayside communication

Proceedings of IEEE Vehicular Technology Conference (VTC), 2002
Audio frequency train-to-wayside communication used in mass transit systems is subject to interference from harmonics of power and propulsion systems. The interference limits data rate in present modulation schemes. A multi-carrier modulation scheme, which offers higher data rate while ensuring orthogonality with interference, is presented. >

Orthogonal multicarrier modulations in satellite uplinks

International Journal of Satellite Communications and Networking, 2014
SUMMARYIn this paper, we analyze Orthogonal Frequency‐Division Multiple Access and Single‐Carrier Frequency Division Multiple Access as alternative physical layer schemes for the up‐link of a satellite network. Both orthogonal frequency‐division multiple access and single‐carrier frequency division multiple access are orthogonal multicarrier ...

An introduction to multicarrier modulation

IEEE Potentials, 2000
OFDM is a powerful modulation technique that increases bandwidth efficiency and simplifies the removal of distortion, due to a multipath channel. Advances in fast Fourier transform technology enable OFDM to be efficiently implemented in hardware, even for a large number of subbands.

Comparison of transmultiplexers for multicarrier modulation

ICSP '98. 1998 Fourth International Conference on Signal Processing (Cat. No.98TH8344), 2002
In this paper different transmultiplexers for multicarrier systems are compared. Starting from a unified approach to multicarrier modulation using wavelet bases and digital filter banks three different multicarrier systems are embedded in this context: discrete multitone (DMT)/orthogonal frequency division multiplexing (OFDM), discrete wavelet ...

An adaptive modulation scheme in multicarrier modulation system

Proceedings 7th International Conference on Signal Processing, 2004. Proceedings. ICSP '04. 2004., 2005
An adaptive modulation scheme is applied in multicarrier modulation system to improve the system spectral efficiency along with unequal error protection (UEP) to meet the different quality of service (QoS) in transmitting data. Power control zone (PCZ) is employed to make the improvement of system performance in terms of average BER or BPS.

Constant-Envelope Multicarrier Modulations vs. Multicarrier Modulations in Non-Terrestrial Network Scenarios

2026 IEEE Aerospace Conference
Some recent work highlighted the potential advantages of constant-envelope (CE) multicarrier modulations (CE-OFDM and CE-SC-OFDM) in various wireless scenarios. The strengths of CEmulticarrier modulations have been recognized in terms of nonlinear distortion immunity and improved multipath resilience owing to the augmented diversity against frequency ...

New Multicarrier Modulations for 5G

2016
Recent advances in filter bank multicarrier (FBMC) techniques are presented and compared with the conventional cyclic prefix (CP)-OFDM approach, in the context of 5G. After a brief description of some adaptations of CP-OFDM, FBMC combined with offset-QAM is considered, pointing out the crucial issue of subchannel equalization to compensate for the ...

Signal processing for multicarrier modulation

Conference Record of Thirty-Second Asilomar Conference on Signals, Systems and Computers (Cat. No.98CH36284), 2002
Multicarrier modulation is emerging as a preferred line coding method for digital subscriber line (xDSL) systems. An equation error filter structure is proposed to enable factored polynomial modeling of the transfer functions of the transmission path and the echo path. It exploits the multicarrier signal structure and an assumed system configuration to
