"WCDMA Downlink Capacity of Cigar-Shaped Microcells Using Soft Hand ..." posted by ~Ray
Posted on 2007-12-15 14:16:57

This cover presents a class-based downlink capacity estimation technique with several modifications to the command CBQ (Class-Based Queuing) principles to ensure its applicability in a mobile environment. Instead of the fixed bandwidth used in wired links a simple analytical expression for the maximum available resource of a radio downlink is derived in the cover. The resource-sharing calculate for each categorise is then defined as the total resource allocation for that categorise divided by the maximum available resource. Analytical prove shows that the class-based downlink throughput can be expressed as the weighted sum of the resource-sharing factors of all classes. CBQ-based downlink capacity dimensioning including estimations on the average be of connections for different classes and calculations for the estimated downlink throughput in times of congestion is presented using the analytical copy derived in this study. A simulative evaluation is provided to show the accuracy of the analytical copy. When the downlink becomes congested the simulative throughput is approaching to the estimated result and is restricted by this value. A simple CBQ-based call admission hold back (CAC) algorithm is developed in our simulation model. In this paper the downlink sector capacity of a cigar-shaped microcells using wideband code-division multiple-access (WCDMA) with soft hand-over (SHO) mode is analyzed. The two-slope propagation loss with log-normal shadowing is used in the analysis where a model of eight cigar-shaped microcells is utilized to calculate the downlink sector capacity. The performance of the downlink is studied for different sector radii standard deviations of the shadowing and propagation exponents. It is open that for a sector range higher than 940 m increasing the sector range will reduce the downlink sector capacity. Also it is found that increasing the value of the propagation parameters will reduce the downlink sector capacity. In many cases the downlink sector capacity ordain be code limited since the theoretical downlink sector capacity is higher than the be of codes assigned to each sector. The high theoretical downlink sector capacity is due to the low determine (0.06–0.1) of the WCDMA orthogonality factor of rural zone microcells. Note to users: The section "Articles in Press" contains peer reviewed accepted articles to be published in this journal. When the final bind is assigned to an air of the journal the "bind in Press" version will be removed from this divide and will be in the associated published journal issue.

Richardson’s Web site the governor was a nominee for the allocate in 1995. 1997. 2000 and 2001. The ’95 nomination was forwarded to the Nobel committee by six academics and politicians. The nomination cites Richardson’s status as an international and Hispanic leader who “embodies the characteristic of both an idealist and a pragmatist…Richardson not only articulates his vision he helps make it happen.”In ’97 Richardson was favorably compared to Martin Luther King Jr. The nomination touted the then-UN ambassador’s globe-trotting diplomacy and hostage rescues as well as his promotion of democracy and human rights. Curiously it also cited his advocacy for NAFTA. The ’00 nomination was submitted by 23 nominators all but four of whom were Democratic members of Congress. The nomination cited Richardson’s “achievements” in Congress in foreign affairs and while he served as Secretary of Energy and concluded: “account Richardson is realizing the kind of humanity that can alter a global difference.”The ’01 nomination emphasized Richardson’s bring home the bacon on nuclear proliferation noting: “Bill Richardson has shown his fight in the struggle for humanity by shining the beam of reason into those corners of the world darkened by nuclear be.”SFR contacted Brooklyn Law School Professor Emeritus Henry Mark Holzer cited as a nominator in three of the four nominations but he said he doesn’t remember signing on.“I have no recollection,” he says adding that he does bequeath representing Richardson in court in the early ’90s when the Legislature passed a law that prohibited the use of money raised for a federal race in a state campaign. At the time Richardson was reportedly considering a run for governor.“There may have been some kind of petition with a whole lot of names on it,” Holzer says of Richardson’s Nobel nomination. “I’m a very very check conservative. I used to represent Ayn Rand. I’m a member of the Federalist Society…and so this sort of sounds out of character for me to say the least.” He adds. “I may have said it sounds like a great idea to me [but] I don’t remember signing anything.”
