Two-Dimensional Permutation Vectors’ (PV) Code for Optical Code Division Multiple Access Systems [PDF]
Entropy, 2020 In this paper, we present a new algorithm to generate two-dimensional (2D) permutation vectors’ (PV) code for incoherent optical code division multiple access (OCDMA) system to suppress multiple access interference (MAI) and system complexity.

Quantum communication using code division multiple access network [PDF]
Optical and Quantum Electronics, 2020 For combining different single photon channels into single path, we use an effective and reliable technique which is known as quantum multiple access. We take advantage of an add-drop multiplexer capable of pushing and withdrawing a single photon into an optical fiber cable which carries quantum bits from multiusers.

A Framework for Code Division Multiple Access Wireless Power Transfer [PDF]
IEEE Access, 2021 The availability of energy is one of the major hindrances to unlocking the massive potential of electronic devices. Powering a highly connected network of devices requires multiple access and a wireless power transfer (WPT) solution that is scalable and ...

Information Leakage Rate of Optical Code Division Multiple Access Network Using Wiretap Code [PDF]
Entropy, 2023 Secrecy capacity is usually employed as the performance metric of the physical layer security in fiber-optic wiretap channels. However, secrecy capacity can only qualitatively evaluate the physical layer security, and it cannot quantitatively evaluate ...

Spatial Modulated Multicarrier Sparse Code-Division Multiple Access [PDF]
IEEE Transactions on Wireless Communications, 2020 This paper proposes a novel spatial-modulated multicarrier sparse code-division multiple access (SM/MC-SCDMA) system for achieving massive connectivity in device-centric wireless communications. In our SM/MC-SCDMA system, the advantages of both MC signalling and SM are amalgamated to conceive a low-complexity transceiver.

Quantum internet using code division multiple access [PDF]
Scientific Reports, 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 ...

Spatial Modulation Aided Sparse Code-Division Multiple Access [PDF]
IEEE Transactions on Wireless Communications, 2018 In order to support high-user-load multiple-access (MA), we propose a non-orthogonal MA scheme based on a beneficial amalgam of spatial modulation (SM) and sparse code-division multiple-access (SCDMA), which is termed the SM-SCDMA. Hence, SM-SCDMA inherits both the merits of SM with single radio-frequency MIMO transceiver implementation and the ...

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.
