Quantum internet using code division multiple access. [PDF]
Sci Rep, 2013 AbstractA crucial open problem inS large-scale quantum networks is how to efficiently transmit quantum data among many pairs of users via a common data-transmission medium. We propose a solution by developing a quantum code division multiple access (q-CDMA) approach in which quantum information is chaotically encoded to spread its spectral content and ...

Spatially Modulated Code-Division Multiple-Access for High-Connectivity Multiple Access [PDF]
IEEE Transactions on Wireless Communications, 2019 In order to take the advantages of spatial modulation (SM) and support the multiple-access (MA) communications requiring high connectivity, we integrate the SM with DS-CDMA to propose a SM/DS-CDMA scheme, which is in favor of attaining both antenna diversity and frequency diversity. Associated with the SM/DS-CDMA scheme, a range of linear and nonlinear

Wideband code division multiple access [PDF]
Proceedings RAWCON 2001. 2001 IEEE Radio and Wireless Conference (Cat.No.01EX514), 2000 We present an overview of some of the key characteristics of a wideband code division multiple access (CDMA) system. Among the topics that are discussed are the effect of spread bandwidth on performance, the use of multicarrier CDMA, and the use of multicode CDMA.

Time-Hopping Multicarrier Code-Division Multiple Access [PDF]
IEEE Transactions on Vehicular Technology, 2007 A time-hopping multicarrier code-division multiple-access (TH/MC-CDMA) scheme is proposed and investigated. In the proposed TH/MC-CDMA, each information symbol is transmitted by a number of time-domain pulses with each time-domain pulse modulating a subcarrier.
