MC-CDMA (MultiCarrier Code Division Multiple Access), currently regarded as a promising multiple access scheme for broadband communications, is known to combine the advantages of an OFDM-based (Orthogonal Frequency Division Multiplexing), CP-assisted (Cyclic Prefix) block transmission with those of CDMA systems. Recently, it was recognized that DS-CDMA (Direct Sequence) implementations can also...

The usability of technology has put a new spin on education, redefining the role of educators and reshaping classroom learning experiences. A major movement today is the integration of technology into the classroom. Many universities, colleges, and community colleges are investing a great amount of money, effort, and training in developing innovative ways of using technology to increase student...

Incremental deployment of a new network service or protocol is typically a hard problem, especially when it has to be deployed in the routers. First, an incrementally deployable protocol is needed. Second, a study of the performance impact of incremental deployment should be carried out to evaluate deployment strategies. Choosing the wrong strategy can be disastrous, as it may inhibit reaping t...

This paper aims to demystify the performance of SystemVerilog and UVM testbenches when using an emulator for the purpose of hardware-assisted testbench acceleration. Architectural and modeling requirements are described, followed by a recommended systematic approach for maximizing overall testbench acceleration speed-up and achieving your ultimate performance expectations.

Traditionally, mobility in ad hoc networks was considered a necessary evil that hinders node communication. However, it has recently been recognized that mobility can be turned into a useful ally, by making nodes carry data between disconnected parts. Yet, this model of routing requires new theoretical tools to analyse its performance. A mobility-assisted or encounter-based protocol forwards da...

An overview of a system for building detection and description using multiple views is given and its performance is evaluated. Use of cues from sensors such as IFSAR is included and helps improve the performance substantially. An option for user assisted operation is also described which is able to produce highly accurate models with relatively small efforts from a user.

This study was designed to assess whether the effects of computer-assisted practice on visual word recognition differed for children with reading disabilities (RD) with or without aptitude-achievement discrepancy. A sample of 73 Spanish children with low reading performance was selected using the discrepancy method, based on a standard score comparison (i.e., the difference between IQ and achie...

—In this paper, aiming to improve the quality of video transmission while satisfying the delay Quality of Service (QoS) requirements, we propose an efficient cross-layer assisted video transmission scheme by jointly considering the video coding rate and the available power resource. We jointly analyze the effects on the performance of video transmission from video coding rate at the applicatio...
