Performance Evaluation of Low Density Spreading Multiple Access [PDF]
, 2012 In this paper, we evaluate the performance of Multicarrier-Low Density Spreading Multiple Access (MC-LDSMA) as a multiple access technique for mobile communication systems. The MC-LDSMA technique is compared with current multiple access techniques, OFDMA

CDMA Transmission with Complex OFDM/OQAM
EURASIP Journal on Wireless Communications and Networking, 2007 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 ...

Wireless Multicarrier Communications via Multipulse Gabor Riesz Bases
EURASIP Journal on Advances in Signal Processing, 2006 We introduce multipulse multicarrier (MPMC) modulation, a wireless communication scheme that augments traditional single-pulse multicarrier systems by using multiple pulses at the transmitter and the receiver. The mathematical foundation of MPMC systems

NVIS Multicarrier Modulations for Remote-Sensor Applications [PDF]
Sensors, 2020 The number of Internet of Things (IoT) devices has experienced a large growth during the last decade, as well as the data volume gathered from remote sensors. Satellites are still a suitable communication method and may be preferable for a remote ubiquitous sensor network (USN), which sometimes are located in places without much communications ...
