- Effects of Call Arrival Rate and Mobility on Network Throughput in Multi-Cell CDMA
- This presentation discusses call arrival rate and mobility. The effect of call arrival rate on the capacity of a code-division multiple-access (CDMA) cellular network is evaluated. First the inter-cell and intra-cell interferences of every cell on every other cell are calculated for a given network topology. Then the capacity region for the number of simultaneous calls in every cell is defined for specified system parameters. This region is used to evaluate the new call blocking and handoff call blocking probabilities. digital.library.unt.edu/ark:/67531/metadc81376/

- Flexible Allocation of Capacity in Multi-Cell CDMA Networks
- This presentation discusses flexible allocation of capacity in multi-cell CDMA networks.

The inter-cell and intra-cell interferences of every cell on every other cell are first calculated for a given network topology. Based on this, the nominal power of users is increased by a factor the authors call the Power Compensation Factor (PCF) which enables small cells to overcome the excessive interference from adjacent large cells. digital.library.unt.edu/ark:/67531/metadc81377/

- WARM SRAM: A Novel Scheme to Reduce Static Leakage Energy in SRAM Arrays
- This presentation accompanies a paper discussing research on a novel scheme to reduce static leakage energy in SRAM arrays. The increasing sub-threshold leakage current levels with newer technology nodes have been identified by ITRS (2001) as one of the major fundamental problems faced by the semiconductor industry. Concurrently, the expected performance improvement and functionality integration expectations drive the continued reduction in feature size. This results in ever-increasing power per unit area and the accompanying problem of heat removal and cooling as stated in J.M.C. Stork (1995). Portable battery-powered applications, fuelled by pervasive and embedded computing, have seen tremendous growth and have reached a point where battery energy and power density can't be increased further according to T. Bell (1991). This raises the computational throughput per watt target for the future technology nodes. SRAM arrays which are used widely as a system component, such as caches and register files, in both high-performance and portable systems, are getting to be dominant power consumers because of their large capacity and area. Hence any reduction in cache energy can result in considerable overall power reduction. The authors propose a novel circuit technique using depletion mode devices, to reduce the static energy of SRAM array in an on-chip by 90% without any performance impact. digital.library.unt.edu/ark:/67531/metadc96819/
