Implementation of CWDM technique in access network.
Publication Type: Conference
Source(s): EPJ Web of Conferences. 2017, Vol. 162, p1-4. 4p. 3 Diagrams, 1 Chart, 2 Graphs.
Abstract: The Coarse Wavelength Division Multiplexing (CWDM) system presented in this paper has several distinct characteristics from the standard CWDM system. One of them is the channel spacing whereby it uses smaller channel spacing compared to the standard sy...

Codes in the Space of Multisets—Coding for Permutation Channels With Impairments.
Publication Type: Academic Journal
Source(s): IEEE Transactions on Information Theory. Jul2018, Vol. 64, p5156-5169. 14p.
Abstract: Motivated by communication channels in which the transmitted sequences are subjected to random permutations, as well as by certain DNA storage systems, we study the error control problem in settings where the information is stored/transmitted in the fo...
On Ergodic Sum Capacity of Fading Channels in OFDMA-Based Cognitive Radio Networks.
Publication Type: Academic Journal
Source(s): IEEE Transactions on Vehicular Technology. Nov2014, Vol. 63 Issue 9, p4334-4343. 10p.
Abstract: An orthogonal frequency-division multiple access (OFDMA)-based cognitive radio network (CRN) is considered where cognitive radio users (CRUs) can only access the frequency bands not being occupied by primary users (PUs) while keeping the cross-channel ...
Pseudo-Lattice Treatment for Subspace Aligned Interference Signals.
Publication Type: Academic Journal
Source(s): IEEE Transactions on Vehicular Technology. Nov2014, Vol. 63 Issue 9, p4729-4734. 6p.
Abstract: In this paper, we propose a channel transformation technique for joint decoding of desired and interfering signals in an interference alignment scenario consisting of $K$ users with multiple antennas. Our technique, i.e., pseudo-lattice treatment, is b...
A Channel-Hopping Multichannel MAC Protocol for Mobile Ad Hoc Networks.
Publication Type: Academic Journal
Source(s): IEEE Transactions on Vehicular Technology. Nov2014, Vol. 63 Issue 9, p4464-4475. 12p.
Abstract: Although multiple channels are supported in the physical layer, the IEEE 802.11 MAC-layer mechanism is designed for a single channel. Exploiting multiple channels enhances spatial reuse and reduces transmission collisions and, thus, improves network th...
Joint Opportunistic Beam and Spectrum Selection Schemes for Spectrum Sharing Systems With Limited Feedback.
Publication Type: Academic Journal
Source(s): IEEE Transactions on Vehicular Technology. Nov2014, Vol. 63 Issue 9, p4408-4421. 14p.
Abstract: Spectrum sharing systems have been introduced to alleviate the problem of spectrum scarcity by allowing an unlicensed secondary user (SU) to share the spectrum with a licensed primary user (PU) under acceptable interference levels to the primary receiv...
Performance Analysis of Linear Cooperative Cyclostationary Spectrum Sensing Over Nakagami- $m$ Fading Channels.
Publication Type: Academic Journal
Source(s): IEEE Transactions on Vehicular Technology. Nov2014, Vol. 63 Issue 9, p4748-4756. 9p.
Abstract: This paper deals with performance evaluation of linear combination-based cooperative cyclostationary spectrum sensing (CCSS) when both sensing and reporting links are characterized as independent (and not necessarily identically distributed) Nakagami- ...
Radio Channel Allocations With Global Optimality and Bounded Computational Scale.
Publication Type: Academic Journal
Source(s): IEEE Transactions on Vehicular Technology. Nov2014, Vol. 63 Issue 9, p4670-4680. 11p.
Abstract: The radio channel assignment (RCA) in wireless networks is an optimization problem that is often found NP-complete. For networks of practical sizes, various heuristic algorithms are used to solve it. However, there are two major issues: finding a globa...
