Hierarchical Genetic Algorithm For Dynamic Channel Units Allocation in TD-CDMA/TDD System
, 2009 Hierarchical Genetic Algorithms (HGA) as a tool for search and optimizing methodology have now reached a mature stage. The minimum resource facility to carry user traffic, termed a channel unit (CU), is composed of a one time-slot and one code in the TD ...

Spectrum trading for non-identical channel allocation in cognitive radio networks
, 2013 In this paper, we investigate spectrum trading via auction approach for exclusive usage spectrum access model in cognitive radio networks. We consider a realistic valuation function which depends on channel capacity, delay sensitive and delay-insensitive

Interplay Between Phase Evolution, Fe Migration, and Oxygen Redox in O3‐Type NaxFeyMn1−yO2 Cathodes
Advanced Functional Materials, EarlyView.Why do Na‐ion battery cathodes, that are compositionally closely related, follow different structural paths during battery operation? This work shows how Fe content controls when iron atoms migrate from their original sites. Early migration locks the layers and blocks key phase transitions, whereas delayed migration permits fuller structural ...

Dispensing with channel estimation: differentially modulated cooperative wireless communications
, 2011 As a benefit of bypassing the potentially excessive complexity and yet inaccurate channel estimation, differentially encoded modulation in conjunction with low-complexity noncoherent detection constitutes a viable candidate for user-cooperative systems ...

Optimally Joint Subcarrier Matching and Power Allocation in OFDM Multihop System
EURASIP Journal on Advances in Signal Processing, 2008 Orthogonal frequency division multiplexing (OFDM) multihop system is a promising way to increase capacity and coverage. In this paper, we propose an optimally joint subcarrier matching and power allocation scheme to further maximize the total channel ...

A Fuzzy-based Dynamic Channel Allocation [PDF]
, 2015 In traditional wireless networks, fixed allocation of spectrum is one of the main reason causing low utilization of spectrum. In order to solve this problem, a new wireless communication model has been proposed, which called Cognitive Radio Networks (CRN)

Approximate minimum BER power allocation for MIMO-THP system [PDF]
, 2008 This paper proposes a transmit power allocation (TPA) scheme based on multiple-input multiple-output (MIMO) Tomlinson-Harashima precoding (THP) structure, where a TPA matrix is introduced to the conventional MIMO-THP.
