Evaluation, Construction, and Verification of a Subchannel Steady State Heat Transfer Code for Plate-Fueled Reactors [PDF]
Several high performance research reactors use plate fuel that is clad with aluminum and cooled with forced convection of subcooled water. High resolution multiphysics simulation tools have been developed to allow the performance of the core in these ...

Joint access control and subchannel allocation scheme for ofdma femtocell network using a truthful mechanism [PDF]
Femtocells are low-power cellular base stations that can improve indoor coverage and offload data traffic from the macrocell network. Nevertheless, access control that has strong impacts on interference mitigation is still an important issue for the ...

Bit Loading Algorithms for Cooperative OFDM Systems
We investigate the resource allocation problem for an OFDM cooperative network with a single source-destination pair and multiple relays. Assuming knowledge of the instantaneous channel gains for all links in the entire network, we propose several bit ...

Performance analysis of greedy subchannel allocation schemes for adaptive OFDMA systems [PDF]
Subchannel allocation schemes for OFDMA (orthogonal frequency division multiple access) systems with adaptive transmission are investigated. The analysis involves two scenarios: single-hop transmission and dual-hop relaying transmission.

Channel-aware subchannel renumbering and downlink burst allocation for IEEE 802.16 OFDMA system [PDF]
碩士本論文是以IEEE802.16標準為基礎並且在實體層為OFDMA技術下,探討如何在點對多點的WiMAX網路架構下,設計可提高Downlink subframe利用率的資源分配演算法:Channel-Aware Subchannel Renumbering與Channel-Aware Downlink Burst Allocation 。Channel-Aware Downlink Burst Allocation是考慮SSs在Downlink之資料量,BS如何分配Burst的大小、形狀以及位置。因為,
