On-Line Arithmetic for Detection in Digital Communication Receivers: Next generation communication systems based on WCDMA Wideband Code Division Multiple Access are being designed to increase data rates by orders-of-magnitude and enhance performance significantly in order to support real-time multimedia services. However, the increased complexity required by the algorithms to support multimedia capabilities has not been supported by hardware...; Tags: W-CDMA, Multimedia, Rice University; White papers
HP Helps Rice University Create a Powerful New Environment to Leverage the Shoah Foundation's Holocaust Testimonial Archive for Research and Discovery: Since the Shoah Foundation's priority is to see this important historical archive incorporated into curricula, it turned to Rice University, University of Southern California USC and Yale University to help develop some test projects that would leverage the Visual History Archive into their learning environments. To help the projects get...; Tags: Rice University, Hewlett-Packard Co., Environment, Storage, Hardware; Case studies
HP Enables Rice University to Support Shared Research Computing and Continue Its Contributions to High-Performance Computing: Rice University is consistently ranked as one of America's best teaching and research schools, despite its small size relative to major universities with PhD programs in the U.S. The mission of the Computer and Information Technology Institute CITI at Rice is to foster and develop research relationships between faculty and...; Tags: Rice University, Hewlett-Packard Co., High-performance Computing, High-performance, Computing, Leadership, Management; Case studies
Opportunistic Fair Scheduling Over Multiple Wireless Channels: Emerging spread spectrum high-speed data networks utilize multiple channels via orthogonal codes or frequency-hopping patterns such that multiple users can transmit concurrently. In this paper, a framework is developed for opportunistic scheduling over multiple wireless channels. With a realistic channel model, any subset of users can be selected for data...; Tags: Channel, Rice University, Wi-Fi, Wireless; White papers
Power Efficient Broadcast Scheduling With Delay Deadlines: This paper presents a framework for the design of minimal power schedulers that satisfy average packet delay bounds for multiple users in a Gaussian wireless broadcast channel. The authors completely characterize the achievable region in the multidimensional delay-power space, and present schedulers that achieve the boundary regions. The optimal schedulers...; Tags: Rice University, Performance Management, Wi-Fi, Wireless, Human Resources, Workforce Management; White papers

Bayesian Blind Parafac Receivers for DS-CDMA Systems: This paper proposes a new Bayesian blind detection/identification algorithm for CDMA system in presence of spatial diversity at the receiver. Such algorithm provides good performance even for short frame length (typically, 10 symbol periods) and for large system load. Furthermore, simulation results show that the proposed method is close to...; Tags: Algorithm, Rice University, Bayesian, Engineering; White papers
pathChirp: Efficient Available Bandwidth Estimation for Network Paths: This paper presents pathChirp, a new active probing tool for estimating the available bandwidth on a communication network path. Based on the concept of "Self-induced congestion," pathChirp features an exponential flight pattern of probes one calls a chirp. Packet chips offer several significant advantages over current probing schemes based on...; Tags: Estimation, Rice University, Bandwidth, Network, pathChirp, Networking; White papers 2008-01-01
Design and Scalability of NLS, a Scalable Naming and Location Service: This paper sketches the design, and presents a scalability analysis and evaluation of NLS, a scalable naming and location service. NLS resolves textual names to the nearest of a set of replicated objects associated with that name, and is designed to scale to the dimensions of a world-wide service. Applications...; Tags: Rice University, Scalability, NLS; White papers 2008-01-01
Rice University's GIS/Data Center: How Do We Do GIS?: The distribution of GIS services in academic libraries has taken many forms; where as some libraries opt to provide a full array of GIS services, others offer mainly on-line reference material. This paper will describe the experience in implementing GIS from a central library location. The paper would attempt to...; Tags: Rice University, GIS, Software; White papers 2006-07-18
TCP-PARIS: A Parallel Download Protocol for Replicas: Parallel download protocols have the potential to reduce file download time and to achieve a server-side load balancing in replica systems, such as peer-to-peer networks, content distribution networks and mirrored servers, by simultaneously establishing connections to multiple replicas and downloading disjoint file parts in parallel. This paper presents TCP-PARIS, a...; Tags: Rice University, Network, Replica, Construction, Servers, Networking, Hardware; White papers 2005-07-01
Analysis of Decision-Feedback Based Broadband OFDM Systems: In wireless communications, about 25%of the bandwidth is dedicated to training symbols for channel estimation. By using a semi-blind approach, the training sequence length can be reduced while improving performance. The principle is as follows: the detected symbols hard decision are fed back to the channel estimator in order to...; Tags: Rice University, Broadband, Training, Analysis, Workforce Management, Human Resources; White papers 2005-06-22
